Eric, I haven't used them (yet), but I have seen Lambert's products in person, and they are super bright. They are very popular with the street rod crowd. Most of those cars have minimal taillights, and they use the LEDs to get the maximum brightness out of them. They are not off the shelf LEDs from Radio Shack. Here's the link: http://www.lambertenterprises.com/ LEDs will not place the same load on the blinker as the incandescent bulbs. If you replace all the bulbs in the signaling system with LEDs, you will need to use a device to place that load on the system, or use a flasher designed for an all LED system. Hotronics offers them: http://www.hotronicsproducts.com/lighting.htm Reading up between those two sights should provide the information you are looking for.

I'll assume for the moment that you've replaced the front turn signal, tail, backup, and license plate bulbs with LED units? I've seen LED units w/a grouping of aprox 10 LEDs in use in a friend's taillight but they were deemed too dim. They were an inexpensive off the shelf item. Can you refer the brand and/or specs of the units you have in your '62? I picture them being pretty effective in a '62 tail lamp cone. Are there LED units that allow for a seperation of LEDs so that one lamp can act like a dual filament bulb for the brake lighting, or do the LEDs simply increase in light output? The instant on and off of LEDs has a safety quotient in alerting the already awestruck tailgater that the massive gunsight tail lamped vehicle ahead of them has just dropped anchor. Thanks, again.

Especially in the case of the generator driven Imperials. But if it must be done, then a relay is definitely the way to do it properly. There are some very good solid state relays out there that can do the job without having to deal with contacts that require cleaning or replacing over time. If anything, the ideal situation is to decrease the current load on the charging system for better performance and stability. (fuel economy too - an alternator at full field will require from 10 to 40 HP from the motor to turn it depending on its rated output) This is why I have changed the bulbs on my 62 from incandescent to LED based. Aside from having a shorter time constant when turning on (Incandescent lamps require a period in time where the filament has to get hot enough to glow - LED's light up instantly giving the drivers behind you as much as a half second more to react.) LED's reduce the current demand on a charging system by 30%. ----------------- http://www.imperialclub.com ----------------- This message was sent to you by the Imperial Mailing List.
