End of the day, the surface finish didnt inspire me with any confidence to follow through on my D3s lights. Id be pretty ****ty if they ended up looking like my spotlight cover did - at least I can cheaply replace that - not so cheap for the D3 and in the end I decided it wasnt worth the riskQuote:

40 minute job this morning to replace old D2S globes with new ones.
Globes were $181 from Powerbulbs UK and arrived in 5 days.
Old ones looked OK until put next to the new ones so we will see how they go.
And to avoid confusion next time, I put the date on the cover (and did the same with the high beam).

Bi-Xeons?
keen to learn how the new ones compare. I'm about to place an order with power bulbs for a bunch of stuff, once I save some $$$
I did a decent night drive last night, and even my wife asked what I'd done to the headlights.Quote:

Good to know. Curious to find out if it is the same D2S xenon globe for the normal xenon headlights compared to bi-xenons.Quote:

A bit like a halogen that is under-run (dimmed) deposits filament on the inside of the glass making it look silver.Quote:

Not particularly relevant to headlamps, but an illustration of the peculiarities of the way discharge lamps degrade.
It's easy not to notice the degradation of HID headlamps as it is an incredibly gradual process. That makes it blindingly (excuse the pun) obvious when you replace the lamps as suddenly your light output ~doubles. Of course when you replace them with souped up lamps and the immediate reaction is "wow these Philips blind-o-matic 4000 lamps are awesome!", but in reality compared to what you just took out a new set of original lamps would be pretty much just as amazing.
Halogens dim over time also, but it's fractions of a fraction compared to the ageing process a HID lamp goes through.
Well I bit the bullet and placed order for new xenon globes, LED high beam, cornering and fog as well as LED side lights plus all th canbus gadgets to suit.
$969 worth from powerbulbs.
They were a bit painful to deal with but got there with them in the end.:bat:[bigwhistle]
Wish I'd ordered new globes when you did. They are $234 for a pair now [bigsad][bigsad]. I wonder why these can't be purchased locally?Quote:
