krymsn Posted May 12, 2005 Share Posted May 12, 2005 Hey, On the inside of my GS3 the tail light out light comes on peridically. When I look at the tail lights it doesn't look like any of them are out. What is causing this? Thanks! Quote Link to comment Share on other sites More sharing options...
TurboGS300 Posted May 12, 2005 Share Posted May 12, 2005 Are you using any LED bulbs? Are all your bulbs OEM? What year is your GS3? <_< Quote Link to comment Share on other sites More sharing options...

It is a 2000 gs 3 and I've had it for roughly about 2 weeks. Quote Link to comment Share on other sites More sharing options...

So if a bulb has a high resistance it can trigger the dash light. Quote Link to comment Share on other sites More sharing options...

Easy enough to fix... Little screwdriver or steel wool to scrub up the contacts. Quote Link to comment Share on other sites More sharing options...
WhiteSC3005SPD Posted May 12, 2005 Share Posted May 12, 2005 I had that exact same problem on my 1990 LS400. The tail lamp indicator was illuminated on the dashboard. I checked each tail light bulb with a multi-meter. All were fine. I cleaned all the contacts. Still the tail light wouldn't go on. I then noticed that one of the wires going to the light fixture had a connector that was screwed into the plastic base of the lamp holder. There was a second wire and connector leading from that screw to the bulb. After spending an hour trying all kinds of things, I took out the screw and analyzed the two connectors -- and found out that there was a slight amount of corrosion between them. I cleaned the two wire connectors with emory paper, put some lithium grease on them to prevent new corrosion - and the light worked perfectly.

Will this alleviate the problem also? Quote Link to comment Share on other sites More sharing options...
