Anybody know how long the battery in a Cat like that would last with the

Depends on too many variables. How old the battery, how big, how many
haz lights, what kinda bulbs, etc. My '91 toyota p/u's fairly new
battery will go stone dead with haz lights flashing, overnight. All
my bulbs are incandescents.

Anyone know if there are approved LEDs that can be substituted.

Just recently I came across backup/reversing light replacements that have
built in beepers. With just a simple bulb changeout my van now has backup
beeping.

I'd consider replacing the flasher bulbs with LEDs if they met DOT specs
because they *have* to last longer in emergencies. I'd be a little
concerned that they might negatively impact the flasher module because of
their different electrical profile.
