Strangeness with indicators...

[Lwanmtr]

Yeah, I've had the headlight switch out..all the connectors looked good and the switch had no heating evidence.

I just checked an old headlight switch connector to see if it's possible to install in more than one way. It is Not. Do your headlights function properly?

Yep, all the lights work properly, so do hazards and turn indicators...just the markers being weird. One thing I note is that they arent getting full power, the markers are dim when they are flashing like that...but bright when turned on normally.

Okay, that sounds like back feeding. Definitely try removing the front indicator bulbs.

Dave, I'm assuming this is because of the D in LED, diode. The mod works because incandescent bulbs don't care about the direction of current flow. Is there some other way to wire this or select a different type of LED that could get around the problem?

Not sure if a bi-directional LED would work with that modification. It also depends on the low resistance of the light bulb when not powered (just lights on, no turn signal).

I installed a little circuit that drives each side marker using the lights and blinkers as signals to that circuit. All four of my side lights have that circuit since I have all LEDs. I think it was one IC to make two circuits work. It needed a constant power wire also.

Ok....I removed the front indicator lights one at a time..and it seems theres something in the front harness going on cause with the bulbs out I get only the rear indicators flashing.

I'll try and dig into that tomorrow and see if its a fault with the harness or if that mod was done.

Is there any corrosion present in the those front sockets?

Also try reinstalling the OEM 1157 bulbs. Make sure the nubs on the side of the bulbs are in the correct phase position too. They are not the same height on each side. Wait is it possible you installed the wrong type LED in the front sockets. If that were to happen and you used a 1156 style LED in the front Sockets, the center contact of the 1156 base could bridge the Double contacts in socket base. This would cross feed the Park/tail and side markers.

Sockets look ok. The correct LEDs are in the front (two contacts). The original bulbs were dead.

Just to confirm, with the Front LEDs removed, all the remaining lights functioned normally?

When you get back to it, try reinstalling just one front LED at a time, perhaps you can isolate a side that's causing the issue. Those front sockets can cause weird things to happen.
