Anyone have a list/links for rear LED Bulbs that work, I want the entire set, fog,reverse and braking.

Cheers

[oakmere]

I have led led bulbs for the rear tail/stop. But they illuminate the dash lights when braking and the lights are off. Apart from this they are fine and no more melting rear lights. If you find some that don't do that pleas let me know. Mine were an e-bay special cost about £12.

[gav89]

Sounds like they might need resistors on them ??

Yeahhhhhhhhhh I just want something that works straight out the box. There must be a solution out there cos I've got LED sidelights and they work great

Hi Gav,

 

Set I had lit the centre high level break light up dimly all the time, far from ideal, went back to standard.

VX electrics are strange

[mbes2]

What's wrong with normal rear bulbs ?

[Bargi]

They heat up the plastic socket they sit in, melt it slightly and you break the bulb trying to change it.

[gav89]

Yeah Bargi, hit the nail right on the head. They heat up too much and considering I'm about to seal the lights further to stop water getting in, I figure LEDs are the way to go cos they generate way less heat and need less air vents

[oakmere]

Mine don't cause the centre to light up all the time. I agree there must be a plug and play solution. I think the big players phillips and osram do them but they are £30-40 so pricey. I think mine need a diode not a resistor. As power is feeding back through the brake circuit to the tail light.

I got mine from here and they work perfectly.

Although they don't seem to have any on their website any more... :S

Yeah those guys dont seem to have any stock at all.

Anyone got any links out there for some guaranteed working LEDS????

[Mazzy]

Any solution on these as i just found out my rear sidelight and brake light are not working. Had a fiddle round the boot and unscrewed the holder to find smashed bulbs, removed lights and cleaned out broken bulb glass pieces and found the plastic surround had melted, filed this and finally ready for bulbs.

 

Used the search feature on here but it seems likes its been a while since anyone as raised this issue. What is the fix for this? LED or stand bulbs? Dont want them melting again.

 

What LED bulbs? CANBUS or non CANBUS?

I have led stop tail bulbs but the light up the dash lights when I brake and the high level tail light is in very dim with the side lights. I know a diode would probably cure this but it would be nice to have a true replacement led bulb. Ring and Osram now produce them so it might be worth spending a bit more for these.

[Mazzy]

Hmmm, well I just put an order in for those on eBay. Did email the company prior and they were happy to assist if they didn't work as expected. Will update once I fit them.

[oakmere]

Keep us updated

[Mazzy]

Update...

 

Stuck the LED bulbs i got off eBay in and the centre brake light is on with when sidelights are on. With brake lights on they get brighter as does the centre brake light.

 

I'm thinking if I wire in a wedge bulb into each circuit of the tail lights then these will soak up the extra load that is being passed to the centre brake light?

 

I've ordered 2x these: http://www.ebay.co.u...=STRK:MEBIDX:IT

 

I'll attempt soon as they arrive but can't seem to find anyone online that has done this. A friend told me it can be done as he has done it like this on his Astra but

that does not have a dual filament (sidelight and brake light together). 

 

Any electrical engineers on here? HELP HELP, ADVISE !!

LEDs are simply diodes that happen to emit photons. Diodes don't generate much resistance, so a diode in an otherwise open circuit is basically a short circuit. In order to successfully drive an led,you need to regulate either current or voltage. The most stable systems employ constant current. To achieve this,you will need a DC-DC constant current driver in your power supply.

[Mazzy]

Is a DC-DC driver available for cars? I can only see ones for Home use. Also where does it need to be fitted? One for each circuit as left and right are on two separate fuses?

 

I just dont want my tail lights melting internally anymore than they already are.

I know its not a VX but been reading the following thread on a forum and the addition of a wedge bulb or similar on both tailights worked.

Is it because the wedge build is also a resistive load....... We put resisters on the LEDs we build into the stuff at work.

[Mazzy]

I'm assuming that any incandescent bulb should work, yes the bulb should take up the extra load. I should get the holders before the weekend, will try and work on them at the weekend... Unless someone is certain it won't work.
