M4 LED Passing Lamp Module - 4.5"

A few years ago I replaced the sealed beam lights with LEDs from Amazon for my 93 Heritage. While brighter than halogen units, the beam was scattered. Based on the performance of my Denali D4s I purchased for my BMW GS, I purchase the M4s. The M4s are brighter and actually have a defined beam pattern compared to the Amazon lights. Very happy with the purchase.

Perfect fit, looks great, super bright

Replaced my stock head light with the Denali M7 after the lens was shattered by a stone. Also replaced my passing lights at the same time. I installed the H4 adapter so the low beams stayed on with the headlights and had my passing lights flashed to always stay on. WOW!!! What a difference. I now have illumination out approximately 25 yards to the right and left of the bike and full coverage in front to approximately 600 yards with pure white light and NO dark spots in the field of view. This combo and set-up really lights up the night. I’ve never been this comfortable riding at night and now see wildlife in the fields to the side and a clear view of the road in front as if it’s daylight. I didn’t know this was possible. Had I known, I would have made this change years ago! Highly recommend Denali lights.
