Hi David,

So this got interesting.

I grabbed a multimeter and checked the following:

1) I removed both fuses for left and right, turned the lights on via the steering stalk and checked for voltage where the fuses are usually inserted. One of them, I think RH had a roughly 12V reading, the other one was dead.

2) I put both fuses back in, went under the bonnet to the bulbs, disconnected the wire plug from the bulbs and with the lights switched on, measured the voltage there. Both left and right lights read a 12V measurement. 

​This is odd right? Why would one of the fuse ports be dead but power is going to the light at the front? 

Anyway, I took both bulbs out, and sure enough they were blown and I have an emergency bulb which I plugged in (only one at a time as I only have one spare) and low and behold both lights shine a lovely light. 

So for now, that's great news and I'm about to head off to Halfords to grab a new set.

However, it's strange for the following reasons:
1) why is one of the fuse ports not showing voltage but the light turns on 
2) why did both bulbs blow at the same time given that they were both replaced as a set only 8 months ago. Decent bulbs too, not cheap.

It could of course just be an innocent coincidence - that's certainly how I'll treat this for now, but I think there might be an underlying (small) electrical problem at play.

Either way, new bulbs for now, and I'll wait to see how they get on.

Edit/Update: Bulbs replaced and now working.
