There are newer LED packages that fit in without any hassle.

That's encouraging. But how do I know which ones will work? I really don't want to do this trial and error process. I want to buy something I know will fit, work properly and not cause other problems.


What LED package did you try?

I didn't try any of them. Some, not all, online sellers would include a disclaimer to the effect that the product may not fit all applications. The well known brand names that I mentioned earlier either didn't list the H11 for my application or specifically stated that they would not fit. In comparing the halogen bulb to the LED bulb it seems pretty obvious that the cooling fan protrudes further from the back of the bulb than the plug on the halogens. And that's what prevents re-installation of the back cover.

There are other drawbacks which you pointed out in another thread in the 200 forum.

Now I see some LED replacements that are similar in construction to the H11 halogens. That is, they are L shaped which suggests they might fit. But they have fins to dissipate heat. This seems less efficient than using a fan. In either case it leads me to wonder, where does the heat go? The bulbs in this headlight assembly are completely enclosed.

The solution would be a redesigned back cover for the assembly that would allow for the heat to exhaust. I doubt that will happen.

I'll stick with the halogens for now.
