Specific Problem w/signal lamp operation 92 Peterbilt 379

You missed the point of this thread. Have to run one incandescent on each side to get the blinkers to blink

 

Having gone through nearly the same thing on my 94 t600 and 98 t800, i do. kw had the indicators in cab be incandesent to provide the resistive force.

The solution IS a proper led flasher, but the ones in stores dont have a low enough resistive load trip

Option 1, kit with inline resistor

Option 2 a real LOW load led flasher.

On all my stuff i run leds in rear and bulbs in front. For me its easier and cleaner to change an 1157 in a “lolly pop” light on the front fender then a rear sitting under a trailer any day. . I haven’t done this personally but a friend of mine just spliced an 1156 into the pilot light pin on the old 3 pin flashers under the dash and says that alone gives enough resistance to run 100% leds.

 

My thing is I like the look and longer life of the LED. Pete uses this stupid small bulb in the indicator. KW uses a bulb for similar to one for my gauges. I think a 194. At any rate it does provide enough draw as but no use in a Pete. Nothing wrong with an ol school light in front that’s where I would put it . For some reason I get to thinking I don’t match that way. Silly I know. I have thought bout a lollipop on my mirrors and don’t want a led there cause it will be too bright. An 1156 used to be just about right there. I do know it’s a pain in the Johnson I have also considered using the bulb type lights as kinda under glow or what have you.
