I have over 200k on my original burnt-out D light. It’s one of those things I know I can rely on 100%. @Bigtex, that’s truly a rare occurrence… I’d replace with a known-bad bulb and keep an eye on it.Toyota endurance is legendary.
The "D" lamp in my Hundy went out 7 years ago, and with no servicing or maintenance involved, the lamp is STILL out with no signs whatsoever of it coming on again.
