If a decent LED could be fitted it should make the fr200 a more effective
tool...

HUH? An 1157 is a 12 volt automotive turn signal lamp. It's an S8
envelope and is over an inch across and runs 7 watts or so.

The lamp in a FR200 is a 5 mm long grain of wheat incandescent with
wire leads. There is some sort of circuit to drive it, because the lamp
is running on about 2.5 volts, with about 2 volts difference between
the the + side of the AA batteries. (The lamp runs on either/both the
AA cells and the rechargeable NiMH pack).

BTW, there's a spare lamp in there behind the pop off lamp holder, in a
little recess in the radio case.

But that 7 watts will really light things up.

Someone was talking about using LED's for incandescent bulbs. If you
want to do this the forward drop on them is typically around 1.3 to 1.8
volts. You just need a series resistor to limit the current usually
around 12 to 18 mA. Digi-key will list them with there typical voltage
and current ratings so you can find one for your situation.

Well those units take 2 to 4 "cells" or 3 to 6 volts. The current will
be higher than a normal bright LED so you will need to pay attention to
battery life.
