Hey!



My HID headlights have started to randomly turn off while driving.



It will usually flicker on/off for a second before staying off. They turn straight back on again after turning the lights on and off, but will start doing it again shortly after. Its not both lights in unison either. One goes... then the other.



It appears to be triggered by G-forces/movement as it often flicks off when i make a sharp turn or go over minor bumps in the road.



Anyone know what could be causing this or of a good auto-electrician in the Brisbane area?



I can't find anything on the forums except someone in Sydney with the same issue on a V35 that had zero responses.



Thanks in advance for any help!


Sounds like it's the lamps. Have you tried another lamp? Turning it off and back on makes the ballast kickstart the lamp with an initial high voltage discharge. It's more likely your lamps would both go out so close together rather than your ballasts.

Replace the lamps.

Make sure you get colour matched ones

I had the same issue with my Stagea running Xennons, and they would both go out when driving at night. Fixed by replacing the old ones with new ones.

I guess we don't know how it is. :yucky:

Actually, while it's fresh in my mind, not that I need to buy any now but I'm a little disappointed with the high beam performance of these headlights. Even my BA lights up a street better with its high beams. I suppose that's more of a limitation of the headlight mechanism but as far as squeezing the most performance out of the lamps themselves, which ones do you recommend Chris?

I have seen LED lights in these. dont seem to be that bad.

HID bulbs pulse when they need to be replaced. They often don't "burn out" perse, but the chemical reaction inside the bulb reaches its limit, and needs to turn off to rewind the process. Replace bulb, It will be fine. Note: don't touch bulb with fingers, or it will go pop.

What high beam halogens? I thought the headlight mechanism just repositions the HID bulbs up a little higher? Hence my question. I'm seeking the best performing bulb for the job.

Ahh the G37/V36 are bi-xenon. The cutoff shield drops when you high beam.

Look at the link I sent you, there are some 'higher output' bulbs but they cost a pretty penny. I think you'll be happy with the Philips Xtreme (since it's closer to 5000K than the Osram Night Breakers).

Yes, good quality (genuine) bulbs are expensive. I've been through $150+ worth of ebay xenon bulbs and can tell you to go genuine from the get go.

One seller sent me 3 4300K bulbs, all different shades of white/yellow. What a waste of money!

To add, switching from ebay to Genuine Philips D2S gave a very noticeable improvement in light (colour, brightness, more evenly spread beam). Same projector/headlight.

That's why I'm advising to go genuine, I've already been though the shit so you don't have to!

Exactly why I asked. :)

I can't remember what my V36 came with off the boat but I'm fairly certain they were Osram bulbs. Anyway, when the time comes, I'll seek out the Philips ones.

I replaced the D2S bulbs in my 5GEN Liberty last night (have to get to the headlight via wheel well, shitty clips makes life difficult). Lights were so dim I couldn't see at night, the driving lights were brighter (country car so assuming lights were on all the time).

Chucked those Philips D2S replacement bulbs in = can see now.

So which ones of the bulbs did u buy? my stock ones on the v36 are not bright enough imo...

I thought he mentioned that in the last line of his last post?

uumm yeah he mentioned its philips but that brand has more than one type of bulb...just wanna know which has most output so i can spend my money wisely... :)

See his post in #12 above. Philips Xtreme.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
