I have a car (Toyota RAV4 hybrid), where nearly all lights are LEDs but for some reason Toyota engineers decided to use incandescent bulbs for the rear number plate bulb and some of the indicator bulbs.
I know that at least the rear number plate bulb may require frequent replacements because it is continuously lit (at least when the luxmeter in the car decides it's dark). But what I do not know is how long these indicator bulbs last.
On one hand, indicator bulbs are lit only very rarely.
On the other hand, indicator bulbs are cycled often, and my understanding is that incandescent bulbs don't like frequent cycling.
So, how many kilometers/miles can I expect the incandescent indicator bulbs to last?
I have never had an indicator bulb fail in a car, but then again I have not driven any single car for more than about 80 000 km.
Judging from the question Rapid Turn Signal, it seems to be the case that indicator bulbs can fail.
