Bathroom light

If you are near a dealer or the West Runton camping/caravan store they  will have what you need the bulbs normally should just pull out of their housing ,they usually have two prongs and  are 10watt

You can usually get them on line as well.

Google 'caravan light bulbs' and a whole list of suppliers pops up.

Just identify the bulb you need as they are all generic.

Failing that takes the removed bulb to your local dealers.

Are you getting 12 volts when you switch the light on? Or .... looking at it the other way round, does it work if you apply 12 to the (removed) fitting?... 

Only tried to switch it on when plugged into mains. Cannot test it otherwise as caravan is in compound 30 miles away.I have trawled through ever caravan accessory/spare outlet site on the internet and still cannot see a replacement light like this one. It is about 3 inches square and looks like a circuit board. Must admit I was surprised to see it when cover was removed.My best bet would be the call my dealer service department for advice.

Thanks everyone for your help.

As it's in the bathroom does it has a pull switch? On at least one caravan and on our last motorhome the ceiling switch failed rather than the light. Easy enough to replace from the likes of B&Q for a couple of quid.

Sounds like a LED light, search for 12 volt caravan shower light on that well know web site I saw one for £15, unscrew the light from the ceiling pull the wires through unplug the leads plug in the new light and re fit, remember to fit the wires the right way round as unlike a normal bulb electric only flows one way through a diode BUT I would test the circuit first, do you not have a leisure battery?

I purchased these for my Delta earlier this year. Are they the same as yours?

Simon,it could be like that from memory. I will go to caravan soon to check it out. I will also get a new pull switch because that packed up too at the same time the light did. Light has its own switch on cover but the pull switch and that could be related. 

Not always the case now with some caravan LED's I have just replaced two amber LED side marker lights on my caravan and they are not polarity dependent. This surprised me ?I found this out when I tested them before fitting. They don't have colour coded wiring on them either, both tails being Orange.

I can only think that there is some sort of electronic component in the tiny circuit board that corrects it when energised. 

My light switch has also packed up in the past. I found out that it was the tension of the spring in the switch. I pulled the spring apart slightly to expand it, reassembled the switch and so far all is OK.
