unbranded Other P21w 1156 12v Led Yellow Bulb Rear Reversing Universal Beeper Buzzer Light Reverse Beep

This bulb does not fit my car becuse my car has slot in bulbs.So I added a new bulb holder for this bulb.It seems to give two types of sound. Sometimes a fast beep. Other times a slower buzz.Not too loud, not too quiet.

Compact size, fits my cars holders easily. Fitted as reversing light and lights up whole street hihihi

Works very well, passed the MOT with it. I feel that the bleeper is too quiet but not too intrusive like a lorry reversing alarm. Probably is ok for people who walk behind you while reversing that it might alert them in a subtle way.

This system is such a clever solution to an ongoing problem where I live. Driving a small van and having to negotiate reversing off the road and up my drive during the chaos of the twice daily school run has become hazardous because of parked SUVs, nippy children and parents on their phones. The clearly audible attention grabbing warning can only be a good thing. Five minutes to install. Job done, risk reduced.

Very good and does what it says however when put inside and covered you can barely hear it, need something Lauder

Works fine fitted easily cheap as chips

Not the brightest but reverse alarm is great.

Does the job but not as load as last ones when fitted
