Thing is the old globes turned off too. It's what they do. Just you won't notice it normally, because lows and highs both being halogen bulbs will be the same colour.

Now he'd be noticing the change in colour. Probably also a period of NO LIGHT at all when flicking back to lows.

Hello,

Based on a 93 ED Falcon

procedure is... under black cover beside battery attached to mudguard is 4 relays... 1 yellow 3 grey... the middle grey is the low relay...

this 4 pin relay needs to be exchanged with a 5 pin commonly blue relay that has an "87a" contact in the centre...

under the header tank there is an empty clear plug t arrangement with two female spade contacts in it... from my schematics I have traced out you can either buy this yellow fuse (which i have heard about but not seen yet) or just straight bridge it out with a wire link (make sure wire is of heavier gauge to take both the low beams current...

now the lows come on with the low... and both when the contacts are changed over to the high relay...

net jammed up... double post... sorry...
