No the hid's might not fit in a space for an incandescent par36.
The high voltage connector/plug is a complication and may need extra
space. Is the back of the bulb on your plane open to the cowel so that
there is lots of space? I am unfamiliar with your situation.

Some questions on HID lighting. I have a 1974 PA28-151 and would like
to replace my landing light (cowl mounted) with an HID light. I know
about the boom beams, but I also see that Precise Flight makes HID
lighting also, and it's about half the price of LoPresti's.

I looked at Precise Flight's installation manual and noticed that it
was written by Knots2U. In addition, it states that the lighting is
for wing mounting only and for Piper models PA24/30/39 aircraft.

My question is... a PAR36 bulb is a bulb is a bulb, isn't it? Aside
from perhaps the legality of the FAA approving this STC for one
specific location, wouldn't this bulb and installation kit work just
as well for a cowl-mounted light? The specifications for this bulb are
exactly the same specs as for all of the other HID bulbs, i.e. 500,000
CP, 35 watts, 12 volts, 2.5 Amps, PAR36, etc.

Thanks... there is a lof of open space behind the bulb, so much so
that I can get to the back of it to change it without having to pull
the cowl. A good 8-10 inches I would say.

You also need a place to mount the separate power supply, which is connected
via a cable to the bulb. It can be a distance away, like on the firewall,
although you need to watch out for the generation of electrical noise in
your radios/nav gear when doing so.

I paid around $550 each from Xevision, for their brighter 50W bulbs.
