Re: Truck-lite LED lights?
Well LEDs are great not only for brightness, but many use them for their ability to run with about 90% less enegry from the battery and that they last ten times longer than any bulb. Regular bulbs suck power, wasting energy through the filament. LED's are a diffracted mini beam of light.
I've seen red (often most common), green, yellow, orange, and blue. Red, orange, and yellow require the least voltage, but the blue and most greens need about three times what the others do. The latest word is that white is coming out onto the market. Very expensive, but think of the reverse lights that could make! Each color of LED has it's own "angular intensity peaks." You'd recognize this if you ever had one shine right at you, but when turned away, it dims and then has another bright point. Those angles differ by the atoms of the material (I believe a metal) that the beam of energy passes through.
That's all technical, though. If you use LEDs, they work great and look cool. They have to be used in clusters or have an extra diffractions shield. This is usually just the taillight lens cover. If anyone's seen those Pirahna brand LED taillamps, you'd know what I mean. The new Cadillacs have LEDs now -- very noticable when cruising at night -- be on the lookout.
So LEDs, as far as I know, have no drawbacks. They are more reliable than bulbs and will probably outlast any vehicle's life. Well, forget that -- I forgot we have Jeeps.
