I apologise in advance if this has already been covered elsewhere, which no doubt it has, but my searches only resulted in discussions about canbus something or other and LED strips. Besides, as with most stupid questions, you can pretty much guarantee they've been asked before. I just can't find where.

All I would like to know (for the time being!) is what bulb do I need to replace a blown DRL? I have searched on Halfords, etc and it never appears as listed for a Skoda Superb. I don't want anything spangly, just a bog standard replacement. Is it a p21w or have I made that up?

Thanks for any help.

Yep, p21w.

If only my questions about the satnav could be answered that simply...
