    L ED Interior Light Problem

    Hey Guys.

    I went ahead & got some LED festoon globes to put in the front, side & boot, to change them over to LED.
    Easy enough to do. I put them in yesterday arvo when they arrived in the post.
    All went well & I actually prefer the white light that the LED's give off.

    Now here is my problem. With the door closed, the lights still give of some light. So I got out my multimeter.
    With the door open or the light switch pulled out. It gives off 12v. As it should.
    Now with the door closed & the switch pushed back in. I get a constant 7v. Hence why there is still some light there.
    Has anyone else put in LED's & NOT have this problem? I have googled & googled but can't find anyone else with this problem.

    Any hints at what to look for. The normal filament globes don't give any light what-so-ever

    Cheers
    Pete

    later models had a diode on the system to prevent this happening.

    Just splice in a diode on the grey/yellow wire coming up the a pillar on the passenger side.

    Cheers for the reply.
    I had a look at the wires coming up the passenger pillar.
    All iv'e got coming up are 3 x Grey, 3 x Red, 2 x Brown, 2 x Red/Yellow

    I should also say its a 2001 TS City. The rear lights also have a reading of 7.6v when door is closed

    one of the greys should have a yellow stripe on it.
    otherwise you can always put it in just before the front light you should see it there as well. I have done it in both locations but in the a pillar is factory location.

    I went out & checked again. All 3 Grey wires are completely Grey. No stripe on any of them.
    But what you are referring to is the Grey wire going the the lamp holder? Which I can do a continuity test to find the one in the pillar

    Also with a bit more Googling. It's just not a Astra problem. Quite a few other car makes do exactly the same thing.
    Though there fix is to put a 1k ohm resister across the contacts where the globe clips in.

    Maybe they put the yellow stripe on the later models.
    If you pop it on the one going to the front lamp holder that should do they job
