The left and right headlights in my 2015 Holden Captiva keep blowing. They've been replaced many times! Any Fix?
This is something that confounds a lot of car owners. For whatever reason, many cars seem determined to blow their headlight globes at fairly regular intervals. This can be caused by voltage spikes (via a faulty regulator) cheap globes, vibration or moisture in the headlight unit. It's also important when changing globes that you don't touch any part of the glass bulb with your fingers. This can leave dirt or oil on the glass which can then cause a hot spot and lead to early failure.
But sometimes there just seems to be no explanation for the early demise of headlight globes. A more permanent fix is to switch to an LED replacement globe which is expensive (at something like $200 for the globes) but seems to eradicate the problem. Make sure you buy an LED kit that complies with the law on such matters (brightness and colour range) and fit it correctly, but in most cases, it's a simple one-for-one replacement deal.
As an aside, I've seen plenty of headlight globes that have died young and it's always been the low-beam filament that has failed. I'm yet to see a high-beam filament blow first.
