Amazon has the Mag-Lite S5D036 5-D Heavy Duty Cell Flashlight (Red) for $15 with free shipping on $25+. Features a rugged aluminum case, 17" length, water and shock resistant, uses five D batteries and includes an extra bulb.
Mag-Lites tend to have batteries leak when more than 2 cells are involved. I guess that the wrapper on some battery brands (that start with "E") are less than perfectly insulated, and the cells make their own slow drain circuit through the case. This gets worse with more cells, as the voltage is higher plus you get a little less leak resistance with all that cell surface area.
Maybe it's OK if you use one everyday, but I've never pulled a 5 cell out in an emergency that wasn't trashed. Never had a problem with 2 cell lights, which also have the advantage of fitting in any glovebox.
The problem with several cell alkaline powered devices is that inevitably one cell will have a lower realized capacity than the rest and when it drains down to zero, multiple cells in series means a higher reverse voltage will flow through the drained cell creating pressure at a higher rate, and finally, venting.
This would be a nice light if you stuffed 5, 2 x AA D-cell adapters in it and used Eneloops, and replaced the incan bulb with an LED module.
Best used on those people that don't repect your authority.

pen_sq - My 3 C-cell Mag has done that. Thankfully I've moved on to greener pastures.
So I guess this is out?

my girlfriend recommends the 5 cell size over anything smaller.
hehe...
