Installed Sunpie LED's yesterday and today I have B1630, B162C, and B1634 codes (low and high beam control circuit codes). Strangely enough I'm getting EVAP codes as well. Anybody had these errors after installing aftermarket headlights? I bought the cheap pair so I don't have halos or integrated turn signals, so it shouldn't be a wiring issue. I thought Sunpie was going to be plug and play with no issues.

 

swap your stock ones back in, clear the codes and see if they come back. If not, try the sunpies again, if they do then try to RMA them. I've got Pro-comps in mine and have not had a headlight related code.
