bulb blown warning light

the warning light which tells you that the vehicle has a blown bulb is lit, I have checked all the lights and they are all working perfectly, any one got a suggestion (other that removing the warning light!)

(2008 Peugeot boxer 2.2 base for a AS Nuevo)

Have you changed a bulb recently?

No -  although it does blow rear lights with a monotonous regularity, last summer I think it blew three in two months, but no blown bulbs this year just a light telling me that there is one!

My daughter had a Jag which kept showing a bulb failure, even when she had changed the bulb several times. The bulbs were from a local petrol station. In the end, she took it to the dealers who fitted a 'Jaguar approved' bulb and that cured it. Apparently, the 'brain' measures the resistance of the circuit and if it isn't within certain parameters it shows a fault.
The bulbs she had bought were slightly different resistance than the approved bulbs. [can't remember if it was higher or lower]

I was with you on that one Dave myself, but as Frank said, OE is the way to go..........unfortunately.

I had this once and eventually found it was a fog light buld. I had checked all the lights except the fog lights!
Not suggesting you would make the same misake but thought worth mentoning I did not check my reversing or fog lights when i did the light check.

I had a similar issue with an Alfa 156(yes I know), then realised it was a blown rear number plate light bulb I hadn't spotted. So system was cleverer than me!

Hi Sue & Mike
Welcome to the forum from sunny Bridlington

I've had this and traced it to a poor contact on rear offside brake/tail bulb which sometimes came on (tail filament) and sometimes didn't. I fitted a new bulb and sprayed with WD 40 (probably not as good as switch cleaner).

Anyway it all works now

Interesting (but old) thread.

I recently bought my for AS Broadway that raises a Reversing Light Warning every time I put it into reverse. I clears if I power-cycle the Peugeot off/on, but it's obviously annoying.

I removed the bulb: 12V 21W. Cleaned it, measured the resistance at 0.7 Ohm. The bulb works fine but each time I put the van into reverse it raises a dash-Warning (which then needs a van off/on to clear).

I'll try a new OEM? (Peugoet don't make bulbs) bulb and report back. I might then try replacing the bulb with a variable a resistor to see whether I can stop this annoying warning from being raised.

I've certainly experienced similar a few years ago with a car. Bought a replacement bulb, not specifying make - just "Can I have a bulb to replace this one, please?". Bulb was fine - but warning light persisted. 

After a tip (I think on this Forum) I bought an Osram bulb. After fitting it, it worked fine, and the warning light disappeared permanently. Apparently the system depends upon a precise resistance, and anything different will cause the warning light.
