Daf105xf fog lights

just had a new bumper on 58 plate 105 so decided to have fog lights in,only the outside lights work the inside two don’t have bulbs in all you can see is Daf logo,is this how they should be or are the bulbs something else to buy,they’re not cheapos of eBay they’re from Daf dealer

thats how they come

The version you have are for vehicles with skylights ,ie the lights on the roof of the superspace cab…I guess you wanted the drivig /fog light …Which are generally called combi lights …if you have skylights you can’t have the combi lights …

Ours with twin fog activate the inner two with the main beam, not on the fog switch. As others have said, it may be to do with rooflights but it’s cheaper for daf to make just one kind of light and blank it off than make two types of fog light.
