Low beam out on both sides

As Keith wrote, many of us (including me) have had both bulbs blow at once
The old mechanic's explanation is that the current pulse of the blowing bulb takes out the (equally aged and thus weak) second bulb.

Do you have daytime running lights?
If you DO, there's a relay involved in the low beam circuits. (choosing between "On" and "on-if-running")
If you do NOT have DRL, the headlamps are powered through switches and multiple fuses (in series), but no relays are involved.

You learn something new every day.
My fairly well optioned 2006 passenger 2500 has fewer gray relays than my more basic 2004 cargo 2500. DRL's 2004. No DRL's 2006.
So the lesson is replace as needed and keep a spare? Otherwise the stage is set for similar service life on both sides.

Teitur,
IIRC when I turn on the high beams in my 2004 the low beams stay on so not sure how this is causing your problem. I'll check mine and let you know.
Keith.
I believe they are expensive to add using the OEM design/parts. Relays, harness cahnges, etc. are required.
Automatic DRL is required in Canada. I recall some threads about Canadians importing USA Sprinters and needing to add the DRL capability.
An advance T1N section search or Google using Canada and DRL may reveal some part numbers for aftermarket units.
This is a start.

"How to add DRL?"
Personally, i just remember to always turn on the headlights.
(after 40 years of doing so, it's pretty well ingrained)
But i still appreciate the Sprinter's beeper when i forget to turn them off ..

You are right, both low and high beams turn on when I push the lever to get the high beam.
but still the low beam will not turn on until I push the lever to get the high beam.
very odd
Thank you, I will give it a try.
I remember most of the time, but I drive 3 different cars that all have DRL."How to add DRL?"

Everyone else that drive this car forget to turn on the lights (or dont know it does not have DRL).
