H7 LED Arrived - Not sure if I should use it?

I'd just removed the fuel tank to route some wires when my 3S H7 LED arrived in the mail. I figured I might as well toss it in while I've got the bike half torn apart

Now that I have it installed, there are two things that are concerning; Firstly, the Vee2 headlight housing uses a plastic dust "cap." It locks into place with a 1/3rd turn and completely seals the headlight, including the connector. Other bikes use a rubber boot which the bulb passes through.

With this LED, there's no way to reinstall the plastic cap. The small harness exiting the LED prevents the cap from seating. I could seemingly cut a notch in the cap, but I'm not sure I want to. Also, while the bulb could theoretically fit under the dust cap (if it were notched), using the cap would likely prevent good airflow over the LED's heat sink. That doesn't seem smart.

The second issue is that the LED H7 is shielded, meaning the emitters are on only one side with a shield on the other. The regular H7 bulb emits light in all directions. I have the bulb installed with the emitters facing down, which makes the most sense to me. But I'm not sure.

So two questions. What are your thoughts on running the bulb without the dust cap? And which way do you think the emitters should face; up or down?

If that's a cooling fan base, you wouldn't want the cover on there. What is the sight pattern like with all three led emitters on the same side?

It's not a cooling fan. It's a fanless heatsink. In either case, I would think airflow is important.

With regard to the sight pattern, I have the bike in pieces (fuel tank/airbox removed, etc.) so I don't think it's wise to put power on the bike.

I decided to shelve it for the time being. Even though I can't test it right now (the tank is off while I do some farkling) it seems clear that having the emitters on only one side of the bulb is not ideal when you consider the stock halogen throws light in all directions.

Also - this will seemingly be the case for any LED bulb - the Vee2 uses a hard plastic dust cap on the low beam to seal the headlight vs. a rubber pass-through boot. Refitting the dust cap is problematic because (1) the wire exiting the LED bulb prevents the cap from seating without modification to the cap and (2) refitting the dust cap would significantly restrict/eliminate air circulation to the LED's heat sink.

Led facing down. Cap has to be fastened or you'll be changing the whole thing in a month due to dust in the entire optic artifact. Remember that static atracts dust too, the seal is there for a reason.

Are you saying he has it in upside down?

Probably no positive help, but on my Wee1, I've run it up to temp with no gauge console connected at all, air box on the bench, fuel tank hanging, with no issues at all.
And, with the size of that heat sink, any restriction at all to air flow, I believe you will be back in there shortly.
YMMV.

I agree. I don't think it's a good idea to run the bike without the dust cover. Nor do I think it's a good idea to restrict airflow to the heat sink.

The single sided LED really has become a secondary concern, given the dust cover scenario. So as I indicated earlier, I've decided not to install the LED for the time being.

I installed the LED headlight bulbs on my V2 and removed the dust covers. There is no issues whatsoever. I was also unsure about it then I believe it may have been a rep from Cyclops said that it's fine and I went ahead and no issues at all. Just do it and you'll be happy with the results.
