Lawdog138 Posted April 15, 2022 Share Posted April 15, 2022 installed new LED turn signals on my 2022 mack anthem bumper and new ones behind the cab flares. my problem is the regular blinkers on the fenders don't blink but light up when the lights are on! any ideas why?

Joey Mack Posted April 16, 2022 Share Posted April 16, 2022 ok... LED's are "Light Emitting Diode's" Diode's are like check valves for electricity... Positive and negative needs to be known when installing them,,,, is it possible that the Light control module doesnt recognize them? there will be a voltage drop to power them and I bet the LCM see's it.. I really dont know if there is and LED module that you can install as a controller. Back in the day... a few years ago, you could branch off a line and go with it... I have actually ran my own homemade wire harness, and connected it to a relay that I installed, which I connected to the original switch, but used the relay to supply the power rather than over tax the original switch. I recently installed 30 LED's on a W-900 L and did just what I told you, however, the KW is Older.. New trucks SUCK... jojo Quote Link to comment Share on other sites More sharing options...

Adding or changing lights to the existing wiring can cause weird issues. Quote Link to comment Share on other sites More sharing options...
