HID Bulb recommendations

[Jimbob]

Do HIDs age over time/use, or is it they work fine, then suddenly become much worse?

Mine seem fine, but thinking of changing anyway if it will make a difference.  Both cars are 10yrs old.

Youve been thinking of changing em for at least a year now!

Just do it!

Only if it will be worthwhile...

in my experience - yes

there may be false brightness results goiung from old 4300k bulbs to new 6000k ones though

Personally I prefer the slightly blue tinge on the replacement 6000K ones i've put in to the 4300K they replaced.

It seems to me they degrade over time... I haven't noticed that bulbs faded on my car, but replacing them did wonders. I'd recommend it

EDIT: I put 4300  in. I don't want blue I want LIGHT!!! It's still pretty bright blue
