The victim-ahem-beneficiary of some stealth lighting: My '58 Impala Sport coupe. This car is a daily driver, and in the wet and dark Northwest, good lighting is a must. Immediately after obtaining this car seven years ago, I swapped out the old dim T3 low and high beam lights for the more contemporary H4 halogen headlights.
They put out quite a bit more candle power, but the flat glass lens and modern fluting doesn't look right on this car. So what is a hot rodder to do in pursuit of traditional looks but with a need for bright and safe lights? Solution: Install the T3 lenses on the H4 halogen reflectors.
Though not a direct conversion per se (actual halogen conversion kits do exist), the swap is rather straightforward, and the results speak for themselves by providing a better lit road when you're behind the wheel.

3 Probably the safest method to remove the lens from the housing is to use a regular metal cutting disc with a bench grinder. You'll want to use a respirator mask, wrap-around eye protection, and gloves for this job. Go slowly, and rotate the light as you go. The disc may be melting glass more than cutting, but it will get the job done-just use extreme caution to avoid any personal injury.
