my bad, didn't see the other thread where i should have asked the question. https://advrider.com/f/threads/led-headlight-bulb-replacement-modules.948701/ thanks guys for the advice. i was thinking that the base of the H4 LED bulb will hit the inside rear of the headlight bucket - #7 and a round hole has to be cut. so, if not needed, looks like a direct swap. your website has the original and the Ultra. can i go with the Ultra? Darryl. Same here, this whole lock-down, stay-home, stay-in-place messed up everyone's planning. we're just a week away, in full motion and to come to a screeching halt. it sucks but for the sake of the general public and our safety too, i have to pull the plug. hopefully, this crisis will be over in another month. wow....darryl, wish you a quick recovery. p.s. send me PM with shirt sizes so i can send you , s.o. and brian the noobs commemorative tee each. sorry no M but i have S, L, XL and 2XL only. heck, one for Wes also for his outstanding performance riding the 790.
