How long do the Phillips Rally bulbs last?
I typically run my lights automatically just like a motorcycle. I have done this by covering the auto headlight sensor on the dash. I have seen approximately 12 months of service from my low beams doing this. I have had customers lose low beam bulbs at an early fail rate of 6 months, but the average seems to be 8 months plus. To me, once you have experienced the increase in light output you will realize that this is a small price to pay for safety and security of the vastly improved lighting. Bulbs can be changed without tools in a mater of minutes.
