Not if you have a 1998 Defender they don't.
I followed the suggestions here and ordered 4 x T5 dashlights. I thought I was being extra careful by asking the supplier when I ordered if I had the right part.
They just arrived and I now know that what I need is probably the T10.
I have contacted the supplier and am waiting for them to ring back.
Maybe it's the Discos and RRs that take T5s. My Defender certainly doesn't.
The interior lights I got for the Trayon camper at the same time appear to be the right ones.
