idosubaru Posted July 29, 2021 Share Posted July 29, 2021 (edited) Friends 09 Impreza. *ALL* other lights work and new bulb. When the low beams are turned on the drivers side low beam doesn’t come on, the DRL stays lit. The DRL is on all the time. searched other forums but wading through 3,000 simple headlight threads is proving futile Im guessing (hoping) the shop installed the wrong bulb and it’s not working right, I’m looking at it tomorrow morning. Does anyone know if that’s possible - install wrong bulb ? New bulb installed recently by a shop (hence why I’m guessing wrong bulb) Pigtail looks pristine and headlight assembly looks normal no cracking or water/condensation in the fixture.

forester2002s Posted July 29, 2021 Share Posted July 29, 2021 in my experience, when these types of weirdness show up, 9 times out of 10 it is related to a grounding problem. Quote Link to comment Share on other sites More sharing options...

lmdew Posted July 29, 2021 Share Posted July 29, 2021 Swap the bulbs side to side and see if the fault follows the bulb. You will also get a chance to inspect the bulbs and connectors. 1 1 Quote Link to comment Share on other sites More sharing options...

You will also get a chance to inspect the bulbs and connectors. It looks to have a new pigtail spliced in. Is there a way to test for sure if it’s wired backwards? I guess if I compare with a multimeter to the passenger side? But I’m not sure what I’m testing since the DRLs work. Maybe I’m looking for which is ground and see if they’re switched? I’ll see if I can test for ground snd see if the wires look different in anyway. Quote Link to comment Share on other sites More sharing options...
idosubaru Posted July 29, 2021 Author Share Posted July 29, 2021 (edited) When I orient the connector on passengers and drivers side the same way and look at both - the red and black wires are on opposite sides. So I assume a previous shop wired in a new connector and swapped the wires? I’ll swap the wires a little later today.

idosubaru Posted December 1, 2021 Author Share Posted December 1, 2021 The new pigtail was wired in backwards by a previous shop. Compared it to the other side and the wires were opposite. The assemblies were faded and his uncle attempted to freshen them up before, so he decided to get new headlight assemblies which I installed last week. Thanks all! 2 1 Quote Link to comment Share on other sites More sharing options...
