i'd already changed my front sidelights once, for Philips Blue Vision globes. however, i was very disappointed with the colour of the light; it was far from blue, and about as yellow as standard!
so, i bought off ebay, another pair of halogen H6W (also known as BAX9S), this time with much heavier blue tint. the tint is painted on, rather than part of the glass, but that doesn't matter. i only hope they last as long as quality osram/philips globes!
NOTE: LED-style globes are not suitable because of their low 'wattage'; this means they draw very little power, and the onboard electronics will falsely indicate a 'bulb failure' message
the results are very good. much bluer than before, so i've achieved my goal.
this time around (accessing the globes) i thought i'd take photos, to help anyone out that may be interested to take on the job themselves too:
*photo 1: tools required include a Torx #30 bolt bit, 10mm socket wrench, and a #2 Philips screwdriver; a bicycle tyre lever (yellow) comes in very handy too; and have good lighting to work with
*photo 2: working on the L side, with wheels turned full-lock to the R; after removing the 2 screws holding the splashguard (wheel arch liner), I used the tyre lever to pull it out from behind the bumper edge
*photo 3: even when released, the splashguard is thick and hard to bend, but you have to hold it aside to access the bumper retaining-bolts (NOTE: the workshop manual officially asks to remove the wheels, then completely remove the splashguards! but that's a lot more work)
*photo 4: this is the limited view you have to access 2 retaining Torx bolts securing the side of the bumper to the car
*photo 5: these are the 2 Torx bolts on the L side; the nearer one has a washer, the other does not
*photo 6: these are the nuts that the Torx bolts secure to on the L side; the nearer one is a loose nut, the other has the nut fixed to the car
-next, remove 5 Torx bolts along the under side of the bumper (sorry, no photo of these); one is in the centre, one on either side just before the rubber wind deflectors (if your car has them), and one at the far end of each wind deflector which is at the very bottom corner/end of the bumper; if you follow the underside edge of the bumper, you will find them
*photo 7: unscrew the side bolts behind the splash guards; this is quite fiddly, and requires smallish tools, and some dexterity, swearing, and may scratch and scuff your hands; with these bolts removed, you can release the side of the bumper; you can see the elongated holes for each bolt
*photo 8: this is now on the R side (similar to L); there is a metal lip that helps support the bumper against the side of the car
