Hello. I am new to the G6 and this forum. I just got my 09 GXP Sedan a little while ago. I just installed the LED tail lights from PFYC and they are beautiful, however I am having some trouble and wanted to see if anyone else had dealt with these issues. First, the tail light are very bright when I hit the brakes or use the turn signals, but if I turn on my headlights, the tail lights do not light up as expected. Also the rear side marker leds do not light up for any reason, and I'm not sure exactly how to test them. When should the side markers be lit up? TIA for any help.
