thats what i thought ,as it is like that on the reversing light but different on the fog light when you push the clips together and take the bulb carrier away there is only 1 bulb which is a long thin one which i take it to be rear light thats the only one

I gave the answer you need above. Answer is clear. What information do you need more?

Take the one you're referring to out and put your lights on, may find you have a different bulb fitment.

Seems unlikely that your means of accessing the bulb would be different.

They're great aren't they :) nice and clear too.

What model designation is your car? SE, FR etc and SC, ST or 5 door and I'll update the list.

Also will try and do a proper tutorial tomorrow.

A correction to my previous post for leds for the 5 door SE. The festoon bulb for the vanity mirrors was 39mm not 36mm. But by gently bending the bulb holder the 36 fit. Now all the internal lights are LEDs and what a difference it has made.

Sun visor bulbs are festoons not 501's

Reverse light fits as per list but fog lamp I beleve is BAX9S base type

I asked the seller of this bulb if it is canbus or not. He said that it has not got canbus system. So I do not recommend this bulb to you. We have to use canbus bulbs

These are only 6w as well
just checked and mine is H21W
which is going to be a BAY9S not BAX fitting type
lots on ebay with canbus
it wont let me post link as not @15post's yet

You are right. BAY9S lamps are used in our cars. They are also known as H21W. There are lots of the kind of leds at Ebay. But as I experienced before the best configuration for these type of outer lamps is:

1) Must be cree led
2) Alimunium heat cover with reflection cups
3) Canbus sysytem
4) Refractive index optical lens

For example I bought this lamp for reverse light. It is perfect. Now I am trying to find these kind of bulbs for rear fog light.

Dont have a link to those but try this one

ebay Item number 141191988703

2 bulbs set (a pair)

Colour: Cool White
Direct replacement for a standard H21W BAY9s 433D bulbs
Use mainly for fog, indicator and reverse lamps
Brightness Efficiency: 210 LM
Operating Voltage: 12V
Total length: 39mm

IMPORTANT!! These bulbs have already built in resistors and are compatible with "bulb failure" Can-Bus System in 90% of cars , But some modern cars ECU-s can be very picky and you may need to fit extra resistors to eliminate on dashboard computer error message.
