I Googled "Model A LED Bulbs" after reading the May-June 2022 "Restorer" Magazine article about a competition between original and LED bulb types.
This thread came to the top of the Google search.
Recommend anyone to read the article which addresses quite well the light patterns and comparison.
I was surprised to learn that the "focused" LED bulbs (
www.logolites.com) DOES NOT REQUIRE A REFLECTOR - and will work equally well with or without. This LED bulb was declared "winner" of the lighting competition.
Not as reasonably priced as some have indicated above, at $50 each they may be your solution to your lighting AND reflector problems.
