Here's the issue: I bought a pair of LED bulbs for my 91 FJ80's tail lights, and upon installation, the brake lights were flashing with the turn signals. I checked the grounds, and they all seemed fine, so I bought some regular incandescent bulbs to see why my brake lights were blinking with my turn signals, and with 2 Incandescents installed, of course it works normally, but if you have an LED on the left side and an incandescent on the right side (or vice versa), it also works normally. I also noticed with 2 Incandescents or 1 incandescent on on one side, there seems to be a turn signal clicker (the thing that makes noise when you activate a turn signal) in the right rear quarter panel that activates. if there's 2 LEDs, that clicker is not activating in the rear quarter panel. (The clicker in the dashboard always works normally). The only thing I can think of now is that I need a load resistor for my tail lights to have the car recognize a functioning bulb back there. I've also heard that the Land Cruiser's cruise control senses your braking using the tail light bulb current, so the cruise control won't work with my low current LEDs. (Even though my cruise control already didn't work...) Any comments?
