Hi

I was pretty sure there was a post on here somewhere about doing this, but I cant seem to find it

Basically Ive already got the blue dash and air con lights, my hazard switch light has never worked, so thought I would try and fix that and while im at it make everything blue

Ive bought 2 x 3mm Blue LED's which had a max volatage of 4v from what I can see. But I thought stuff it there only 50c each I'll give it a go and hopefully it will only draw a few volts. But its blown the light by the looks of it as soon as I've tried it lol.

Basically just wanted to see if anyone else has done this? I'm guessing unless I can find a 3mm 12V Blue LED im going to have to get a resistor and put it in the wiring before the switch as its the only real place where there is room for it.

The only reason I'm posting this here is because I'm sure I've seen it in a thread somewhere where someone had done this with a 12v 3mm bulb, but it could have just been a normal globe not an LED

any help would be appreciated :(

Thanks

Callan

For any LED youll need a resistor in series to limit the current, go to jaycar or somewhere similar and buy a 220 Ohm resistor that'll give you around 55mA across the LED and itll be all good cost the whole of 20c. Then soldier the resistor to one of the LED legs and wire in normally (make sure you put the LED in the right way as there polarity sensitive)

yeah figured as much. I guess the wedge type ones have a resistor built into the base.

Ill have to wire the resistor into the wire before it plugs into the switch because there is no room inside the switch where the light sits to put a resistor, the legs come straight out of the LED and go basically 180 degrees then straight then 180degrees again, over a very small space

Thats fine but, 220ohm resitor will do the job you say? I could work it out, but if your sure thats what it is, it saves me some maths :(

Thanks

I did mine a while ago and changed the dimister to the a green/blue colour to match the aircon controler readout and the hazzard in red. It was a bit of a fiddly job to get them in the original rubber slieve bulb holders but it looks great now. I also did the AUTO switch on the drivers side power window switch

Alright I sorted it

Got a high intensity blue LED and put it in the holder for the light in both the switches. Then wired a 620ohm resistor into the light illumination wire.

Ill see if I can do a rough drawing

Thats looking at the plugs coming from the car side. The + symbols are the wires in question. I think the demister may be the other way around (Bottom right wire not bottom left) but cant remember and my dash is back together :action-smiley-069:

anyway, it should be the blue with red striped wire. Theres one in each of the plugs, thats the wire for the illumination

Hopefully that helps someone

BTW: sorry about the formatting of the 'drawing', cant remember how to get it to space normally lol

    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go       
    • I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
