Does the 2018 Citigo have two reversing lights fitted please?

Only  one on the  nearside illuminates.

Have a look at what colour wires you have going to the offside cluster. On earlier versions (all I have wiring info for) the wire colour to the reversing light bulbs is black/blue on both sides.  So if there is a black/blue on the offside there probably should be a working bulb there. 

Thanks,I'll have a look asap. 

Yes it has two working reversing lights, at least my 2019 does, so a 2018 should. I've just looked.

 

What is odd is there are three pairs of 21W5 bulbs for brake and tail lights - the upper pair (L+R) come on when you brake as you'd expect. The lower RHS comes on for a single rear fog light (LHS for LHD cars) but the middle pair of bulbs only appear to work as tail lights, which seems a waste. Don't know why they did that,  but sometimes it is the case you can get a cheaper break-price (no homophone pun intended) by buying more of one type even though the individual item ought to cost more (2 filaments instead of one). I was hoping they had some kind of automatic switchover in case of an upper brake light failure, but I strongly doubt it on a cheap city car!

Thanks for your reply,looks like I've got a job on this weekend.

My money is on a corroded connector or bad earth, or possibly the bulb-holder, if it's not the bulb. Shouldn't be too hard - start late morning and you can open some wine by noon...

My 2014 has two, so should the 2018. Must be a fault.
