PARKING BRAKE WARNING MOD
After catching myself trying to drive off with the parking brake engaged a few times, I decided to add a better warning light. There is an idiot light in the dash but I've failed to notice it more than once. Here's what I did.

I picked up this 1"x4" strobe LED light from Amazon.
GPPOWER Universal super thin 6-LED Amber/White 19-Flashing Mode Car Truck Warning Caution Emergency Construction Strobe Light Bar (1pc)

Though I did order a couple of magnetic reed switches, I found it was simpler to just splice into the existing parking brake switch. Easiest place for me was at the switch it self.
Red wire to the OUT side of the switch. Black wire to a ground.(I used the switch mounting itself) Two wires going to switch. One is Hot to the switch when key is On, other gets energized when brake lever is engaged. I used a pin to probe for which one was which. 50/50 chance of being right the first guess so do you feel lucky?
This light has a couple of neat features. It's waterproof supposedly.
It appears to actually be made of a heavier "glass" than cheap thin plastics.
The yellow wire gets touched to ground when the light is powered and it changes the flashing strobing pattern. It is Bright!
For you snow moving types, a couple of these on the ROPS would make good warning lights while plowing I believe.
I mounted where I did because of the convenience of that location.
Though below line of sight, the flashing draws attention readily even in direct sunlight. There is places for a couple of mounting screws but I used double stick tape for now. If that doesn't work out long term, I'll drill the holes in the metal bracket easily.
Soldered the wires, taped up the connection, and called her good.
Start to finish, maybe 1/2 hour.
