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!

Assuming this is a similar system to the Saab bulb failure, the name being a clue. The only way I could keep the warning light off  in the winter was to spray all the bulb holders and bulbs with contact spray from Maplins. The dealers told me decent bulbs would help. I was not being had by that 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 might have been able to run Saab,s but there parts were out of my pocket range. Being in the trade indirectly there were some places you didn't buy bulbs from. One motor factor sold them loose in boxses on the counter. Freshly painted orange bulbs were there specialty.

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.

Is this the triangle light? I have had it off and on since 2015 when the van was new. Peugeot main agent said it's a bulb or bad connection.

Well it happens when I start up with only the day time running lights on. I get rid of the warning by switching the lights on/off several times quickly.

Strange or what.

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.
