Hmmm. wasn't there another light that worked when you filled it's reservoir with fluid.... ANY fluid? Seems like you could couple that with a pullup and do much brighter lighting than just glow /ubbthreads/images/graemlins/grin.gif
I don't know about making it brighter, but the portable 4 inch fluorescent tube black light (that I just happen to have) makes his pajamas glow like crazy /ubbthreads/images/graemlins/wink.gif
Well when your son is old enough for the pull ups You can preform sutch tests.
I would preform sutch tests my self but sadly there not made in my size. /ubbthreads/images/graemlins/icon3.gif
