Review: Quality product - Really good quality and direct replacement for my my revers light p21w .what a difference in light no more yellow glow now its like proper white .my lights are bright .excelent product and a good price too.
Review: They fit and work - This was a repeat order because the first pair worked so well in another application. These I put in rear fog lights because I was fed up with problems with normal lamps corrosion and connections. These so far are working well and passed the MoT so lets hope I don't have to rebuild the lights again next year. They are bright as they need to be and have minimal current draw.

## Questions & Answers

**Q: bought this product, fitted it into the socket and nothing, flipped it round and still nothing, anyone know whats wrong?**
A: Check the spring terminals in the socket. I had similar issues with a standard incandescent bulb. Also had issues with moisture ingress.  I'm using these as replacements for the reverse and fog lamps on an old LR Defender. Brilliant.

**Q: Will it fit mokka 2014**
A: If it take ls the P21 type fitting then yes.

**Q: Hello I’m bought that but the both lights doesn’t work?**
A: If your car has what’s called a canbus system they won’t work without a bit of tinkering. 

 If you swap the wires over in the bulb holder then that should do the trick.

**Q: Would this fit a Peugeot 307 estate sw for reversing bulb?**
A: As long as your current bulb is a two pin 21w standard bulb this will be a straight replacement

Good lights but nit exactly direct replacement. If your car has warnings for bulbs out then you need a power converter, these will through up a fault in the system.
