Interior Reading Lights Problem

[Don1961]

I've had the following fitted for a while now, with no problems.....

Now I'm driving when it's dark I've noticed the following.....

Initially I noticed the front two reading lights were staying lit, but very dim. I've fitted resistors, as per the instructions, and that has fixed it.

However, when I take my foot off the accelerator and brake, the front two reading lights start flickering. When I accelerate again they go out and everything is fine until I have to slow down/brake again.

Anyone had the same issue with LED interior lights or know how to fix it??

Sounds like you have a short circuit developing, try fitting the tungsten bulbs back in and see if it still happens with those.

Have a close look at the printed circuit board, look for white powder or sticky gunge where corrosion is tracking across the soldered points.

Thanks. I'll have a good look tonight.

The car's only a year old but I'll check it all out and maybe try a different LED bulb as well as the tungsten ones

Had a good look at board.... looks OK.
Swapped with tungsten bulbs and they work fine.
I think the issue was caused by how I'd fitted the resistors.... I've now soldered them and it seems a lot better. Though they still flicker a bit... so maybe my soldering isn't brilliant

You can buy LED with the resistors already fitted, just look for CANBUS compliant ones.

Cool. Thanks. I'll have a look

Sorted! No flickering now.
