What is the combined wisdom of replacing headlight bulbs.
Went into Halfords and was told it is advised to replace both headlight bulbs at the same time when one has gone, just don't see the logic in it.
(Apart from additional sales for them)
Any thoughts appreciated?
I always replace them both if easy to access, when you pull out old working bulbs they usually look pretty burnt up.
Bulb brightness diminishes over time. Chances are if you have one new and one old you would notice the colour/brightness difference (more so on xenon)
i've had ones same age and type fail one after the other a couple of times (about a week apart)
but i've had alot more fail just one at a time
so its not really a good enough reason to replace working bulbs.... just make sure you've always got at least one good spare

Other than ensuring a negligable amount of even brightness I see no benefit.
If you got a flat tyre, would you repair the other three good tyres?
What happens if you change both lamps and then a week later one pops? Do you change both of them again?

As said above, ive only ever changed the faulty bulb, and never noticed a difference
INHO its a sales ploy, more bulbs sold, and more fitting charges
I change both if i know they're quite a few years old, otherwise just one.

The only reason I changed both was because I couldn't tell what type of bulb was in there, and when I swapped one for a Philips the colour change was significant (pretty much one blue one orange!). If I had known the original type I would have bought the same one again and left the unbroken one alone.
I replaced both dip beam bulbs at the same time with upgraded Osram bulbs just over a year ago, a few weeks ago so maybe no more than a year after i
had fitted them i had a bulb warning light on dash.It indicated the nearside dipped beam had blown. I was in Leicester at the time and continued to
were i was going for about 15 minutes I parked up and when i set off again the headlamp warning indicated the offside bulb had also failed, I ended up
having to drive home on main beam and fog lights as i didn't have a spare bulb with me .
I realised that it wasn't a good idea to change them both at the same time and also that Osram night breaker bulbs are crap, i replaced them both
with cheap standard bulbs and bought a spare for next time.

What's the collective thought on led headlight bulbs?
I tend to buy one if my car, and a pair if its for the company car.
if the bulbs are the same then there should be no problem, but a lot of folks go for "better" bulbs and then they get a different colour and brightness. for your MOT they need to be the same.
