Phildoe if your having lights issues remove the headlight plugs from the light controller board and plug each headlight connector into the “dome lights” plug, that way when you flip the switch on the transmitter marked “lights they come on and stay on until you flip the switch off or turn off the rc truck. I figured it all out with my Tamiya/HG-P408 hummer unit, oh and FYI the lights controller also includes 6 spots for LED strobe lights!! i installed red/blue custom police ones in my Hummer
