Mi1lion-
what I did was replaced lenses on the rear of my truck(red ones) with lenses from the front of a 57-58 parking lens(clear) and added blue dots to the lenses
and found the Single large 1/2" led bulb with 1157 bases
I didnt make or find a special board like the guys on the 73-79 list are looking for

I'm getting more curious all the time.

Harbor freight sells a LED light for the trailer hitch - $6.49 ON SALE, regularly 12.99. I have used them on our TT and '05 F250. Heres a link to some pics -

(may have to cut and paste. I have modified them to work as they do, the mods are simple, and I have pics I can email with instructions. PM me if interested.

I don't know if the led lamps draw more or less current than an incadescent lamp, but the flasher rate is related to current flow. In older trucks with mechanical flasher units faster flasher rate is due to higher current flow not lower. And in those if you blow out a bulb the flasher stops and the dash indicator stays on. Also if you plug in a set of trailer lights, there is more current draw (all the lights on the truck are wired in parallel) and the flasher blinks faster.
Newer truck may have a solid state flasher and operate differently I don't know.

Correct, the older mechanical flashers do work that way. On some of the newer cars you see one (front or rear) signal flashing rapidly - the other one will be out.
Leds typically draw 20 to 30 milliamps, with typically 4 in series. So with a lamp with say 12 leds, you would draw 3 X 30 ma or 90 milliamps - approx 1 tenth of an amp. Some high output leds may draw more.

The LED tailight bulbs are a good replacement item. They light faster and burn brighter. The quicker lighting translates into more response time for the driver behind you.
Regular bulbs can take up to 1/2 second to reach full output. LED's are instant on. At 65 mph that gives the person behind you another 47 feet of stopping distance which can mean the difference between a near miss and a missing rear.
I saw the difference on a car towing a trailer. The trailer had LED's that lit noticeably before the cars. It was amazing.

I upgraded the third brake light on my Aerostar several months ago with 1156 LED bulbs after the OEM wedge-base socket broke while changing the bulb. I posted a thread in the Aerostar forum and there were several replies.
Search the forum and you'll find the post - there was some good info posted.
