Converting EV lights to LEDs
« on: December 28, 2007, 11:54:56 PM »
Jim Dawson was kind enough to give me 2  LED lamps for my S10 after he spoke on the subject (many months ago).

These are amber colored turn/parking lights for the front.  The http://www.heavy-dutylighting.com part no. is HD1157YSD:



Jim told me i'd probably have to change out the old (1992) thermal flasher for a new digital one because the LEDs use so much less current, the old ones think the bulbs are burned out and don't blink :-)

i happened upon this great article for modifying the blink-rate of a digital flasher in case i need to:

http://www.instructables.com/id/Automotive-electronic-flasher-rate-modification.

It's a simple modification, replacing a fixed resistor with an external variable one to determine/adjust the desired blink rate.  Perhaps the blink rate could be synched with the tempo of the currently playing song   :D   Here's one of the pictures from the Instructable to whet your whistles:



More later...

Great post, Ted.  I found another source for the LED lights called www.superbrightleds.com.  I bought some home lighting bulbs from them and plan to put these on my EV when the time comes.  There are many advantages, as discussed.  Replacing the flasher relay is a small price to pay.
