Gday Folks!

I've noticed lately my headlights have gotten worse.

Are there any ways to bring it back up to scratch?

I've already replaced them with BATMBL's globes however those didnt make any difference so this has lead me to believe it might be the old wiring??

Any suggestions?

Cheers

If the wiring is poor to the std globes there will be less then full voltage to them, there for they are not at bright. The r32 doesn't use a relay for low beam power goes through the switch, so this eventually renders the switch useless and has less then optimum power supply.

Adding relays and a good power source just takes the load off the switch and gives the more power avalible to the globes.

At the moment im putting relays in my R32, also might go to a higher wattage bulb as well to try get some extra brightness as they are quite poor.

Alex would you mind posting your progress with the relays please? I'm planning on doing the same thing but if you're going there first some pointers would be great.

And if you've not yet started, I made a DIY headlight switch replacement thread in the DIY section. Has a few pics that might help things along.

Anyway mate, love to hear which relay you used and where you placed it.

Cheers

Mark

Hi, this is how I was going to do it, twin relays with dual outputs on each, either putting the relays next to the fuse box or behind the drivers side head light. I have 2 narva 40 amp relays, going to use large wiring (5-6mm) and probably 90/100W glabes. I was going to take the signal just from the drivers side head light plug when i cut it off, but now im thinking of taking out the stock wiring and running the new stuff in the factory tubing. Also thinking about removing the high beam relay and taking the signal wire for high beam off there. Also thinking about putting relays in the stock relay box. What ideas you got?

hehe probably a stupid suggestion, but have you tried adjusting the angle screws on the back of the lights? I thought mine were dim, then i figured they were just aimed down to much, and one of them was aimed cross eyed.

Doubt that'll help but its worth a shot

hehe that might explain why my high beams are pointing up.

Anyways i've discovered my wiring on the right headlight is has called it quits (parkies still work though).

What a Pain in the ass... :(

Well by comparison, if I said "me fail English? that's umpossible" would you know where I'm at? ;)

Seriously though, after a few rereads I'm almost up to speed. I'd prefer to replace the factory wiring but I can see it being a pain in the butt. There may be enough room in the dash for one (maaaaaybe two) of the relays - have you considered placing them there?

I like your idea about removing the high beam relay. If you can fit them in the stock relay box, I'd do that.

Are you using 12V direct from the battery or are you tapping something in the dash? I've read that using the constant for alarms and headunits can screw them up by reducing the input voltage to the equipment...?

100W globes sounds nice but I've recently read that guys that have tried them ended up melting/damaging the plastic within the headlight itself. I've not seen it myself but apparently it's a square peg/round hole sort of thing.

You're making me keen again! What did you pay for the Narva relays?

Cheers

edit: great diagram! so for all the guys that haven't seen a circuit diagram since uni, you are drawing 12V directly from the alternator? seems unusual, so I've probably got it wrong. That'd mean you'd need a voltage regulator in series after the split?

I was thinking of keeping the relays as close to the headlights as i can, just so there is less wiring. Just for simplicity.

I still need to check this, i have been installing a new deck and amp today, tommorrow i will have a look at the fuse box option.

The 12v to power the lights them selves (to the relays) im going to take from the alternator (again i didnt explaine my self before, my battery is in the boot, so i cant take it directly off there) Only reason i said alternator is i found a web site that said you can do that. Failing that i will go off the back of the starter motor, this is where the fat cable from the battery goes anyway. If you have the battery in the engine bay take it from there, will be even close from a wiring perspective.

100W globes sounds nice but I've recently read that guys that have tried them ended up melting/damaging the plastic within the headlight itself. I've not seen it myself but apparently it's a square peg/round hole sort of thing.

I have also been told this so i might stay away from this. The relays should give the best power to the globes, with a good alignment should work well, hopefully.

You're making me keen again! What did you pay for the Narva relays?

I cant quite rember now but i think there only around $8 or so, the packets didnt have a price as i got them ordered in.

edit: great diagram! so for all the guys that haven't seen a circuit diagram since uni, you are drawing 12V directly from the alternator? seems unusual, so I've probably got it wrong. That'd mean you'd need a voltage regulator in series after the split?

This could be wrong, but this was my understanding. The alternator has to have a pole where it charges the battery, if you connect to this, its the same as connecting to the battery as its all just 12V and should be a decent sized line (alternators can chage at say 80 amps so has to be a decent sized wire there?) Anyway as i said before just go from the starter motor, or the battery

Cheers (ps spelling isn't my strong point ill try fix it up in a sec)

for the non-electrical engineers out there... will your circuit mean that the low beams will remian on when the high is triggered?

;)

I dont think it will, ill try explaine. The wires that goto the H4 globe (mine are H4 i have read there are a few variations to the R32 head lights) there would be one ground pin, one +12V for low bean and one +12V for high beam. If you were to cut these wires you could use both +12v for low and high to turn on the relays, meaning that the lowbeam circuit that uses no relay will now only have a very minor current draw probably less then .5 amps. The high beam +12V will now also have a very small power draw, even though from the factory this uses a relay. So you can do 1 of 2 things, you can use a relay to turn on the new super duper relay you are using to power the high beams, or you could remove the factory relay, find the switching wire used for it, and use that to switch the new super duper relay on.

hope that makes sense

Cheers

That pic is so good even I could follow it. Best part is using the markings on the relays to save me going crosseyed doing it myself.

I've found I need high and low, as the high beam just sprays light EVERYWHERE, which is great, but you then can see in front particularly well...

So my headlights have decided to malfunction again!!

This time the hi beams are jammed open. what i mean by that is everytime i switch on the headlights (low beams) the hi beams are also on, regardless of which position the hi beam switch is in.

Anyideas on whats causing this?

cheers guy.

I think there is a DIY thread in the Tutorial/FAQ section. I had similar issues with my headlights not coming on, or only one coming on and it was the switch. Find that thread and it gives you a step by step run through on how to fix it (by elongating the spring). Your alternative is to buy a secondhand switch assembly, for about 50-60 bucks from what I heard.

Some idiot had replaced one globe in my car with a 100W bulb rather than the 55W standard, which had, over time melted some wiring and kept melting fuses. I changed this back to a standard replacement globe and funny enough it was actually brighter. Going brighter doesn't mean you have to go up in Watts. You can buy 30% and 50% brighter bulbs at any auto parts store, they are still 55W bulbs, just use a different gas or something for brighter light. I'm happy with the brightness I now have, and it was only like $7 a bulb.

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
