Then when I try to use the turn signal the driver side is just a faint flash whereas the passenger side is a good steady flash. I get the same result whether I use LEDs or incandescent bulbs. I've got a stronger flasher can in my fuse panel. When I use an incandescent bulb it looks like only one strand of the brake/turn signal wire is working, and it's much brighter

You might have a weak ground for that light. | | | | | Joined: Feb 2019 Posts: 4,475 AD Addict & Tinkerer | | AD Addict & Tinkerer Joined: Feb 2019 Posts: 4,475 | Sounds like the wires on the drivers side are switched. The running light circuit is wired to the signal bulb and the signal light circuit is wired to the running light bulb.

Another quality post.

Thanks for the advice....all of you, I appreciate it. It still won't work with LEDs, but at least the incandescent is working corrrectly.

LED lights require a special LED flasher to work properly.
