I have been running the same bulbs for about 4 years. They were working fine on the last coach. Now I am getting a problem where the opposite bulb will flash very faintly when the turn signal is on for the other light.
Example: turn on left signal and the left bulb is nice and bright and working correctly and the right bulb is very faintly flashing.
All other functions work normally .. parking... brake no problem.
I double checked the wiring yesterday.. no shorts everything is golden. I changed out the bulbs for incandescent and they work normal.
I am wondering if I need to get a new flasher.
I might clean the bulb ground contact area today but I doubt that is the problem.. but you never know.. I thought of this after I finished and closed up the lenses
Just in case I did order a new set of LED turn/brake signal lights .. they say 5 watts draw just in case that is the problem.. maybe the older led bulbs I have aren't drawing enough?
