Automatic headlight oddity

Kobra · Jul 28, 2016

Ok... Weird issue... I just noticed today that in automatic mode, my right front parking light is on brightly, but the left front is off. In manual headlight or running light positions, both lights are on, but not as brightly as the one is in auto mode. I've done no troubleshooting yet, because I'm kind of perplexed. Turn signals seem to be working normally, everything seems normal in manual light positions, there's only any problem in automatic mode.

Thoughts?

Sounds like you need to replace the turn signal bulb on the left front. Do both lights flash with the same intensity when you hit the hazards?

I didn't think to check that, will do... But would that even be an issue if the left front turn signal is working? I've got no fast blink, no bulb out warning, none of that.

I am unsure, the circuitry should cause a fast blink if one of the bulbs is completely out. I'm not so sure about if only one filament goes out.

The reason your DRLs are brighter than when the parking lights are on manually is because only one filament is used for parking lights, two for DRL.
