Within the past eight months to a year My RS has blown 3 H-3 bulbs in the passenger side foglight, 2 PIAA's and as of tonight 1 Hella Yellow Star. When they were installed each bulb was handled carefully to avoid contaminating the glass and this particular bulb has seen less than 75 hours of service, I would guess. If any of you lighting guru's have any ideas please feel free to let them loose.
