So first off, I’m changing out all my lighting to Can Bus ready LED. The front turn signals on the backs of my mirrors calls for a P21W, while the rear signals on the rear Tupperware calls for 12093NA. Both bullbs are amber, both run the same power, and both have the same BAU15S base. So what’s the difference, and why aren’t they all the same?
They (BRP) probably just had more stock of one set of lights/globes for whatever reason, so they used them. :rolleyes: It could be that, or as simple a thing as the supplier who provides the front (or rear ;) ) brakes getting a better deal on those globes rather than the others so they used them instead; but since they are 'form, fit, and function' compatible, you should be able to use either, both, or replacement LED's! :thumbup:
Don't over-think it or stress about it too much; if you want to change them for LED's anyway, go ahead & do that, then just......
Ride More, Worry Less! :ohyea:
