Led Trailer lights

[Bigmuz7]

Update .. The X5 (57 plate) wont have them. I made a tidy job of the resistors on an aluminium heat sink from some scrap too

The brakes work fine, as do the indicators, but no side lights.

With everything off you get a pulse through each lamp every few seconds, which is the christmas tree effect Pikey D described

I imagine this is the system testing for bulb failure, as it does, and I have no idea what the fix for that is .. fortunately I have plenty of plant trailers I was intending these guys for anyway ... until some flash git picks up a digger with an X5

If its not a silly question, you did put the resistors in parallel with the indicators didn't you?

Well done Crusher, thanks for that link

No .. because

I never questioned your judgement ... but I'll try that then

Oh sh1t wrong again

Right, just to get this straight, it's a 6.8ohm 25w resistor in parallel with LEDs, NOT a 6.8kOhm resistor in series. If a jobs worth doing, it's worth doing 3 times..................................

Well it still didnt work anyway .. christmas tree effect just the same ... the Bosch must have done something tricky with the leccy .. I'd have thought series would have been the correct procedure, since a direct resistive load is put in line with the supposed 'bulb', but like I said earlier.. surely all the lamps would need a resistor, as each one is detected seperately ?

Time to get googled

Work fine on my Merc ML & Defender but they're not known for technology fortunately. They're very bright & hopefully will last a lot better than the bulbs ever did !!!
