I believe there are 4 of them. Uniden part #BPZY0036001.

I looked quickly on Radio Shack's site, but only saw some 12V
microlamps. The ones in the 895XLT are 8V. The 12V ones would
probably work, but they'd be too dim methinks.

Uniden probably has a ton of them, so give 'em a call and see if
they can send you some replacements.
