I have a 2007 base model Prius 255K, and for some years now it seems I am replacing the bulb in one headlight or the other every 6 mos. Is this typical and/or have others experienced this? ~5 years back I tried the fancy super-halogens and those went kaput quickly. The guys at the parts store said some older model cars don't have the headlight assembly constructed in such a way to support the heat generated, so I switched back to the regular Sylvania bulbs. Still I feel like I should get more than 6-12mos out of a new bulb...no?
t depends on how much you use them. Drive a lot at night? Many hours of use. I too have tried several and have gone back to the old Sylvania standard Halogens. We get about a year out of ours with moderate use. I buy an extra 2 pack and switch both at the same time. They are like airfilters, oil filters and wiper blades. twice a year on wipers and once a year on cabin and engine air filters for me.
Yes, Sylvania. Once my wife decided to use headlights 24/7 it became a yearly replace. Cheap enough, just a royal pain to swap them out.
What are the roads like where the car is driven with the lights on? Rough roads tend to break headlight filaments. I recall having a headlight fail once just from going over a speed bump. OK, maybe it was going to go soon anyway, but the bump was the coup de grace.
