For a start there are no direct replacement LEDs for units designed for
tungsten - the optics on these lights is optimised for a point source
filament. And for things like indictors this is a very real problem in
sunlight etc - the LED replacements simply won't be as bright, or have the
same viewing angle. And it's not just a slight difference either. There
are currently no LED replacements that meet the specifications required by
law in Europe. Completely new lamp units designed from the start for LEDs
are a different matter.

They will also confuse the failed bulb warning system.
