I have looked for 'White' (3 color) super-bright LED bulb replacements.  
Have not found any (yet).

My to-do-list for the e12m is to convert the light over to 36 volts.
Currently I only get my playing done after the kids go to bed and end up
mowing near dark.  I have located 36v replacement headlight bulbs and now
working on finding a 36v replacement for the dash.  I have also snagged 3
36v fork truck horns. Plan on installing 1 of them also.

The LCD readout is on my 'to-do' list.  Actually what I want to do is have
numeric readout of battery voltage and current (same as analog gauges, but
with real numbers). Since I would probably make it microprocessor 
controlled
I would also store the data and be able to upload it to a computer to see
long term trends, etc. Don't ask why, it just interests me...I would keep
the analog gauges as they are a better human interface than digital gauges.
I would replace the removeable 'kick' panel with a new panel holding the 
new
gauges (pointing up) along with a 12VDC accessory plug and maybe some other
things. This way the tractor can be put back to original if I want.
