Aerzetix: P21W 12V Reverse Bip-Bip Rear Alarm Car Warning Buzzer Lamp

I bought 2 of these so that both reversing bulbs would match on my van. Turns out that the sequencing is slightly different on each bulb so instead of them 'beeping' at the same time, they are out of sync and just make an irritating jumble of noise

Works as described.Not loud enough to hear from inside the cab, but can be heard from a good distance behind the vehicle.

My mistake, I thought that all reversing light bulbs where like an indicator bulb, not so, Toyota auris has to be different.Great looking product, could not use it on this occasion

garage had difficulty in fitting them not as loud as I hoped not as bright as I hoped garage had difficulty in fitting them so only fitted one.

Great light and with beeper makes it saver

excellent for my camper
