Finally wired up my reverse lights the other day, from info on posts on here (I get all my ideas from this forum). Mine has never had them and had a blanking plug in the gearbox. I also bought and fitted reverse light bulbs with built in audible beepers from eBay (like you hear on lorries reversing) I was a bit sceptical if they would work so also had some normal bulbs on standby if they did not to check my new wiring and switch out. To my absolute joy and surprise they did work and have to say for me they are one of the best accessories I have fitted on the van (I know, simple things please simple minds and all that!!!) I bought them not for warning people behind you that you are reversing of course which they do, but more for now I can tell if I have managed to select reverse gear, I have always struggled selecting reverse gear normally taking two or three goes at best, gingerly letting the clutch up slowly only to find out I’m still in neutral or in-between gears with that horrible grinding noise. I now have an audible alarm to let me know I have selected reverse gear, so if you struggle to find reverse I can’t recommend these enough.
