Guessing a bit based on usual standards....
T usually means tubular ---is that the shape of your lamp(s) ?
The number, in this case 3.5, usually indicates diameter in 1/8's of an
inch, therefore this would be 7/16" dia - is that what you have?
Xenon is a noble gas. Xenon lamps are similar to incandescent except
for the internal gas.
I've successfully replaced xenon lamps with led lamps of same form.
In my case, they were not T3.5's.
