Headlight wiring question

[geraintthomas]

Hi all,

Would anyone have any idea on how to enable the headlight bulbs to turn on when you switch/flash the main beams?

The reason is that I've sprayed the insides of the headlamps black as they have projectors. Trouble is, the main beams aren't bright due to having no reflectors. The projectors have a bi-xenon operation which throws the xenon light upwards when you flash someone... but only if the headlights are on. If you flash someone when they're off, they don't turn on - nothing happens.

Is there a way of having the headlight bulbs to operate with the main beams?

I'm hoping it's a case of jumping the wires from the main beams to the headlights along with a diode to not allow the headlights to turn on the mainbeams? If so, what diode should I get?

Cheers!
