I think the delay module leaks some voltage even when its off and this somehow keeps the relays activated until the circuit can be broken, which is what happens when you flick the highbeams. Its not enough voltage to activate the relays, but enough to keep them activated once they are on. Of course with the regular sealed beams and no harness the lights just go out because the small voltage leak is not enough to actually light the bulbs. This is my theory on this and my xj is a 2000.

Its probably only some delay modules that leak the voltage and with all these different cheap relays being used in the harnesses, some can be kept activated with just trace voltage and some cant. So, put these 2 variables together and the problem only pops up with some people, not all with the same setup. I guess this is just what happens when you add modern tech to an older system that was never designed to work that way. It wakes up the gremlins.

Same issue. Where is the delay module located? Is it easy to bypass it?

You guys will love going HID projectors. Big difference in safety. I did my own however.

I didn't realize it was that easy.

Basically, take it with a grain of salt. Try it yourself and report back, please! That way we can figure this out.
