Below you will find the differnet models and range of bayonet fitment CREE LED bulbs which we sell, please select your correct bulb fitment for further options. All our CREE LED bulbs are priced accordingly in line with the output wattage.
Bulb types 1156-BA15S/P21W and 1157-BAY15D/P215W are mainly used for brake, fog, indicator and reverse light functions.
The difference between 1156/BA15S & 1157/BAY15D is that 1157/BAY15D is a dual filament bulb that allows two functions from one bulb, such as a sidelight and brake light in one bulb or an indicator and parking light in one bulb. 1156/BA15S does not have this function.
Bulb fitment 581 - BAU15S/PY21W is very similar to the 1156-BA15S/P21W, but has offset pins.
As always, if you are unsure of anything, please just ask us, as we are more than happy to help.
