why waste space with a 9v?
you can get the same setup with 5mm diodes,a switch and watch cells.
my huntley police truck runs 5x 3mm and 3x 5mm diodes from 3 watch cells and a switch.
i built it almost a year ago and i hav'nt swapped batts yet.
another plus to wiring your own is that you wont have the bulky housings,leads and built in resistors...not to mention that 3 watch cells weigh about 1/8 of a 9v.
if you wire your own then you have the ability to mount them where you want them without the housings limiting your posistioning and you will be able to add the resistors ANYWHERE you want.
the only thing left to worry about is switch placement.
