Default Rear Light bulbs need replacement several x a year ?

Hi folks

New to the forum,

We have a 2016 sprinter 3500 I believe it is a NCV3,... and we've replaced all the rear tail light bulbs several times since new. Last year it was about every 4 months a bulb or 2 would die, using high quality Sylvania etc bulbs, correct type etc. we usually replace all the bulbs on what ever side has lost one...but we keep losing random tail light (driving/brake/turn) bulbs way more often than we should be..

Bulb warning lamp is on on the dash also.. never goes away, no Check engine or other warning lamps on. I don't really care about the bulb light I know those can stay on with perfectly functioning lighting out back... just wondering if anyone else experienced anything like this on their similar vintage Sprinters... ?

Cant find any other reports of "chronic" tail lamp bulb failures... so i'm worried we are the lucky ones.

I was considering something like replacing the bulb holder/panels in the tail lights...I see where those are replaceable and now available for about $60-$80, but not sure if that woudl be The solution, A solution or a waste of money and time.. ?


Any advice would be much appreciated and thank you for reading this.

Something isn’t right. Bulbs should last several years. I’d start by checking the voltage at the battery with the engine running. I think anything more than 14.1 volts would be a problem. Get the engine up to 1500 - 2000 RPM for the check so the alternator is at full output.
