definitely not a good suggestion absent any testing with a SPECIFIC LED brand and design
and pairing it with the reflector bowl of that model car. notwithstanding that such an LED
modification is technically illegal in nearly all of the US on public roads, there is no standard
on LED design so the focal point of the LED emitter will almost always produce unwanted
glare.

if you take two magnifying glass models and try to start a fire, the odds are that each
will be held at different distances from the target media. why? focal point

in order to produce a quality light beam, spread and controlled focus (minimum glare)
the light must be calibrated.
