a while back I modified some chrome Lexus style lights for my 306 cabriolet by tinting them red to mimic the style of the newer Peugeot cars of the time (207 / 307) http://s120.photobucket.com/albums/o192/jindal/?action=view¤t=DSC00022.jpg
the problem I had was the indicators would not shine orange enough with standard bulbs so I replaced my rear indicators with SMD led "tower" type bulbs, and although much better than the earlier original types of led bulbs that came on the market they still did not produce enough light to pass as an indicator....... and these were 32 ledSMD tower bulbs at £20 each !!!!!! so I put x2 in both sides , so that's 64 of the little blighters, still not bright enough http://s120.photobucket.com/albums/o192/jindal/?action=view¤t=DSC00221.jpg the problem was that the lens wasn't "filling" with light like a normal incandescent bulb would, so allot of the inner space of each reflector remained either unlit or dim. so I "acquired" 8 batwing luxon leds from a mate who made gantry signs for motorways, the brightest leds you could get at the time, these things were so powerful they needed a large heatsink fitted along with an led driver, with 4 of those put inside each unit stuck to the rear of the red reflector and positioned so they shine direct to the chrome reflector, only then could they be passed off as a working indicator to pass an MOT, doing this involved passing each led through a bulb holder and soldering them in series wile they were inside the lamp themselves, sort of automotive keyhole surgery, despite still being bright enough to look like conventional indicators to a passing motorists they were still illegal, and if I took the car to a proper MOT station it would have failed put simply leds - of the type to replace conventional bulbs just don't give out enough of a wide angle bright light http://s120.photobucket.com/albums/o192/jindal/?action=view¤t=DSC00215.jpg If you look at bespoke led tail lights you will see all the leds facing rearwards because leds have a very narrow viewing angle, - they look bright , blindingly so with some when viewed directly from in front, but turn them to 20 degrees or so and the light almost disappears despite the units you mention having leds set at 90 (ish) degrees to the reflector they are sill only giving out intense points of light that scatter within the lens reflector that will diffuse throughout the inside of the lamp and not a full illumination. the main issue I had still with the mega bright leds was if strong sunlight shone on thee light when the leds were on you struggled to see them since leds produce light on an emitted electrical frequency and not by burning - like the sun. id stick with conventional bulbs until technology moves on a bit.
