I bought a pair to fit as rear fog lights but found they were about the same level of brightness as the LEDs in the standard rear BMW light. However, I did find that the Bullets maintained a high level of brightness when view obliquely, much better than the rear light, so I put them on anyway. My GF (also a biker) says they're remarkably bright, even when drawing alongside.
IMPORTANT: I used the number plate light feed for power (apols for calling this a tail light in the instructions). I did this so the new red LEDs would act as back-up should the tail light fail for any reason.
Here are full fitting instructions as a PDF:
