The headlamps are H4 they going to be changed for Philips LED..The DRL are stock LEDIndeed! What's the betting?
A point of curiosity - are the headlamps using LEDs or not? They do look like the single bulb type - H4 (as opposed to the twin bulb type H7)... If a LED, then they are probably bright enough to not need to use the twin types....
Thanks are there twin headlamps? Never seen them? Do you have a link?Consider fitting the twin headlamp units and using 4x H7 LEDs - that will give amazing illumination! Probably not road legal.
At least you'll retain the electric light-levelling facility with the twin units, so maybe not too dazzling!
