Hi,

Can anyone tell me lifetime of LED bulb ? I bought mine from ultraled.co.uk and one of bulbs lasted something like 45 days ? is it normal ?

Not at all, they are designed to last something daft like 10,000 hrs (basically the lifetime of the car)

It depends on their quality and environment.

Cheaper LED's will be more likely to fail earlier and some LED's do not last long in hot environments (directly next to headlight bulbs for example).

Buy cheap buy twice.

Saying that, sometimes you can be just unlucky and have a failure for no obvious reason.
