Doesn't anybody make a turn signal flasher replacement that just has a timer
built in? The thermal bi-metal units will not work without the "load
equalizers" mentioned in the site. That seems wasteful. Especially if one of
the major benefits of the LED bulbs is the reduced current draw.

Look at this website http://www.myroadster.net/led.asp they discuss
several LED lamps , although mostly for exterior applications.

Chicago Miniature
(
http://www.chml.com/electric/display.cfm?type=led&style=LEDsDiscrete&Subst
yle=T-1_3/4White ),   DialLight, and SPC all make cartridge/leaded style
LEDs  the problem will be mounting them for maximum light use.  I'm
looking at using the High-Intensity White with a modified panel bezel to
replace the entire lamp assembly on the instruments.

If you use LEDs make sure that they have a built in limiting resistor, or
that you use an external one.  Assuming 5MA per lamp at 13 volts the
resistor should be about 2700 ohms and 1/8 watt.  Other wise no limiting
resistor means a one time use really bright lamp
