    Holley Retro Bright headlamp

    I installed a 7" Holley Retro Bright headlamp in my 1982 CM200T. I hope to update this thread with pics and video soon. But first, background.

    The 7" Retro Bright is a standard H6024-style headlamp, same as any U.S. automotive 7" sealed-beam headlamp in terms of size and fitment, including the 3 locating slots on the back for proper alignment into a car's housing. It's on the medium-to-higher end of the price and performance scale for LED headlamps. ($200 each). Yes, you can spend more than $200 for an LED headlamp and no, this does not compete with cheap Amazon/eBay LEDs that will not have clean cut-off, good beam pattern etc.

    The Retro Bright is a collaboration with Morimoto, their name is on the replaceable bulb module, and it's the only LED headlamp you can buy that looks OEM until you send it 12v. It is available in 2 Kelvin ratings, a lower one that looks like a OEM headlamp's and a higher one that's daylight-balanced and offers a bit more lux. I chose the latter.

    Here is a partial list of Hondas that can directly fit this (or, any) H6024-style headlamp:

    CB450K Super Sport - 1972-1974
    CX500C - 1979-1982
    CX500D - 1980-1981
    CB500K - 1971-1973
    CB500T Twin DOHC - 1975-1976
    GL500 Silver Wing - 1981-1982
    CB550K - 1974 -1978
    CB550F Super Sport - 1975-1977
    GL650 Silver Wing - 1983
    CB750 Nighthawk - 1995-2001
    CB750A Hondamatic - 1976-1978
    CB750F Super Sport - 1975-1978
    CB750K - 1969-1978
    CB1000 - 1995
    GL1000 Gold Wing - 1975-1979
    GL1000LTD - 1976
    GL1200 - 1984

    The CM200T takes a 6.x - inch headlamp. I thought I had measured mine prior to purchase but I measured the housing I suppose, which is irrelevant and the Internet didn't tell me what the headlamp size was ... looked like 7" and I plunged ahead, money just flying out of my wallet.

    The CM200T headlamp also has integrated mounting tabs. (And because you can't buy replacements at the auto parts store, these are expensive headlamps.)

    I purchased a "7" Chrome Headlight Rim / Retainer Assembly" from 4-into-1
    https://4into1.com/7-chrome-headligh...0-gl1000-1200/

    As their site says, it's a reproduction of 3 Honda parts: 33101-300-673, 33101-405-671, 33100-371-980

    I can report that the parts are well made, strong, and have excellent finish. The trim ring for example is higher quality than my OEM trim ring.
    This is also around the time I learned none of this would attach to my bike's headlamp bucket.

    But I have a list of bikes the retainer assembly fits, so ... eBay. I bought one from a 1974 CB550, it is stamped
    HM 20M.

    1) I drilled a
    second hole in the back, using a hole saw
    2) I drilled out the 2 mount holes, because my bike's original (yet smaller) headlamp bucket had larger holes and bigger hardware than Honda used for the HM 20M bucket ... and I wanted to retain the larger hardware.

    3) I had to slightly spread apart my bike's headlamp bucket mount bars to accept the larger bucket, and futz with moving the various wires and connectors around to create space for the new headlamp. It's no deeper than the OEM headlamp, amazingly.

    Here’s a video, showing the beam pattern in various levels of light.

    The sharp upper cutoff is a bit disconcerting to me but that is probably the camera. It feels like I'm in a tunnel.

    It's not the camera, better LEDs or HIDs have sharp horizontal cutoffs. In other words it's an illusion of sorts to think light that fades away adds meaningful clarity. This just makes plain what's viewable vs not so much.

    Yes, the "gun slit" takes a few minutes to get used to, especially since I don't yet own a modern car with lights as capable. All of my references are with much dimmer lights that gently fade away from mostly a solitary center blob. They're "more pleasing," in that regard, but only in a way that gives a false sense of security. As a kid I was told, "Don't outrun your headlights" and that's probably what they meant.

    Maybe if I had a fast bike I could outrun the Holley light. But at one point I reached 60mph on the country road with excellent vision. I'd never attempt such a thing with the OEM headlight.

    I can throw bright light down the road as far as I can safely use, without blinding oncoming traffic. The added visibility off to the sides is a bonus. The only way to improve upon that is to spend even more on a light that would not fit inside any motorcycle's headlamp bucket unless the wiring were removed.
