When i installed my spyder headlight i had to wire some of the lights into the running lights after i did that everything worked but i noticed that the driver side running light was a bit dim and that the driverside turn signal indicator stays on when i turn on the running lights. It still flashes when i use my turn sinal but when i turn it off the indicator light stays on. It made my turn signal dim as well. I thought i checked to see if it was the bulb but i might be wrong. Do you think its the bulb, the wiring or something else?

 

Welcome to the forum


Front parking light on that side is Grounding thru the turn signal on that side.

Check your Grounds.

When a light has a bad ground and another light has a good ground then the light with the good ground will glow(be on) when the light with the bad ground is on, as power passes backwards thru the circuit.

This is very common issue when doing trailer wiring
