Yes, this looks really nicely engineered. Like the way a small rectifier bridge is used so same unit works for both polarities. Could have gone further and made one unit for 6 or 12 V, but that would probably take price to over $100.
Funny how the testimonial comments range from nearly as bright as the old one to brighter than a thousand suns or thereabouts.
Not really .
If the electrics were properly maintained then the Led replacement is better than the tungsten globe but not as bright as the halogen globe even when the latter is running at 8 V because of the disgusting state of the wiring.
I get a lot of favourable comments about "how bright" the lights on the M20 are considering that it is 6 V and the answer is always the same.
They look good because they get the full 6 V that they were designed to get not 2.5 that most do due to lack of maintenance.
It seems that every one wants the "mystical miracle magic invention" to fix their lights wen all they need is a little time and some steel wool.
