1156 for the brake lights and turn signals but there are smaller ones in the driving lights and reverse lights...I can;t make out the number on them.

The top light (tail?) is 10 watt, the other 3 (Blinker, rev, brake) are 21w.

No guarantee implied as this is from memory!

the numbers you seek are cast/stamped

right on the bulb holder reflector housings

Right on. The numbers are likely stamped on the bulbs you wish to replace too. And, I think you might find the same info in the owners manual.

Is the number of the smaller ( 5watt ) taillight bulbs. If I recall correctly

[vintage_car]

the housings are burnt...I can't read anything on them and the bulbs aren't coming out easily...

[c.d.iesel]

.....well then

YOU NEED NEW bulb housings, and the correct

lower wattage bulbs so the rear of the car does'nt get bern't.

Has anyone come up with a modern-day equivalent listing for 2K2 lights (Roundie)? I've gotten to your string through the search looking for the correct bulbs with the correct wattage so I don't melt the tail light lense on a long night run. I'm not familiar with the "21CP" notation cast into the reflector - must be wattage and base type?

I believe what is correct is:

Turn Signal Lamp: (21 watt) - 1156

Tail Light: (5 watt) - 1895

Brake Light (21 Watt) - 1156

Reverse Light (15 Watt) - ???

So, is what I have correct? Does anyone have a number for a 15 Watt Reverse Light bulb?

Thanks

According to the BMW Parts Manual.

Brake Light & Turn Signal = 21w

Tail Light can be either 5w or 10w

Reversing Light can be either 15w or 21w

I believe the reverse light is a 1003...shea, shea nee.
