Changed my sidelight bulbs today to laser blue ones purchased for the princely sum of

done the same on my fabia... its good means if weathers dodgy u can get away with having them on but without everyone flashing you to turn headlights off.

Tried leds but they were not great. I got 2 21w led lamps from csm supplies on Ebay to use for rear indicators. They sent the wrong ones which are white instead of amber so they are going back for replacement. Tried one though and it's very very bright. It has side facing leds too but it's pretty directional and my rear indicators are aimed at an angle so they won't do. Hope to put them in the front instead when I get them and i'm assuming the brightness will be similar to the white ones.
