Re: (ET) 36v bulbs

One could also use one of those super high intensity LEDs with a resistor 
to
drop the voltage.

The new LEDs are incredible. I use a bank of three to light the steps to my
work shed, and a bank of six more inside the shed to light the entryway.
They put out enough light to read by (they are mounted on the rafters, six
feet away from the work table) and more than enough to go up the stairs in
the dead of night.

They also consume so little power it's not funny (figure 20ma at 36 volts).
In fact, I leave the led lights on 7*24. Given their current draw, it would
take about three years to deplete the shed's batteries (assuming there was
no sun for the solar panels for 3 years). Six seconds of sun is all I need
on the panels to replace the power used in 24 hours by these lights.

On an ET, they could basically be left on forever.

For the dash light, you can just make a simple 1 resistor divider.  If you
know the resistance of the bulb (by measuring it) you essentially add a 1
Watt resistor in parallel to it with a value of about 1/2 of the resistance
of the bulb.  Here you don't waste very much power.

Hello Jeremy,
  Sorry for taking so long to reply but, it took me a while to find where I
last put some that I bought. I came across some 36v bulbs with the two
contacts on the bottom of the bulb that fits the ET head light socket. The
box they came in is from Hyster, Unisource(TM). I guess they made 36v
forklifts? Is anyone one on the list familiar with Hyster or if they made 
an
36v electric forklift? The part number is  3015692. Description: Bulb 36v
B9.  The only markings on the bulb are "Taiwan" and the code "SP5".
  I bought these at an old Surplus store a couple of years ago, located out
in the very small town of LaVale, MD. I went back to the store on Friday to
find more bulbs and look for other interesting stuff that I really don't
have the room for. When I got to what "used to be" the dimly lit back part
of the store, I fell to my knees... all the old surplus goodies are no
longer there! I almost started to cry. The store manager said it was just
too costly to keep stuff like this around because it does not sell much. 
The
same space he said is now being used to shelf more commonly sold goods that
have a higher turn over rate that generates more revenue for them. I had
bought several old electric motors and many neat old used electrical 
gadgets
and parts from them over the years. Now it has all been replace with the
same hardware and products that can be bought at just about any hardware
store. I really loved those old types of stores.
    Next step would be to find a Hyster dealer and call them and see if
these bulbs are still available. Has anyone found a 36v replacement for the
dash light?
