@BOB WALKER posted:Good question. I unboxed a Williams GP-9 I am saving for a new product conversion and ran it in conventional mode on both AC and DC. Both front and rear lights are on in all three electronic Eunit modes, FWD-NEUTRAL-REV, with both AC and DC power. Never previously gave this much thought. Hope this helps.
OK Thanks Bob. I guess I didn't pay it enough thought before I removed the Incandescent sockets.
