Got myself a set of Speaker lights(8800's). Can't gett highbeams to work. They flash up once and that's it. Has anyone else had this problem or could tell me what the issue could be? Checked plugs and have ground/power. Work fine with regular lights. 2007 Peterbilt 379
thanks

I have them on my 2013 Western Star. Mine work fine except , the daytime running lights lower voltage causes them to flicker, so I have to leave them on all the time. Not enough of a load on the controller, so you may need to put a resistor in the circuit to cause enough of a load for the relay to lock on.

Bit late here but my peterbilt's wiring on the high beam side was backwards...same issue as regular bulbs worked fine. Switched wires in the plug and presto everything worked great.
Peterbilt tech said this has been a known issue for guys switching to LED. -
A bit off topic.... But I have the JW Speaker fog lights. They are the best thing I have ever added to my truck. They light up the road and ditches as though it's almost day time. Love them and would buy them over and over!!
nofilter Thanks this.
