Euro Tail Light Gremlin......
I put the back bumper back on my car early today and pulled the car out of the garage to just make sure everything works correctly. Well I am glad I did, I noticed that when I hit my left directional only one of the yellow bulbs works and that's the one closest to the passenger side, the one all the way on the driver's side did not work. I switched the bulbs around and there is nothing wrong with the bulb. Also, the driver's side marker light does not work, bulb is fine there too. What to do????

Check the harness connector just behind the passenger rear wheel. This connector has a tendency to come loose. I was having intermittent problems until I safety wired the connectors together.

Ok.... I found out that one of the bulbs was bad, the filament was loose.....not your typical broken filament. Now, I am having an issue with the drivers side marker light not coming on at all.
I am not sure and maybe someone can remind me, do the marker lights on the rear fenders, do those only blink when the directionals come on or are they on the whole time your lights are on???

Its a 194 bulb but you need to go in through the tail light to change it.
