Those tail lights could be the brake lights you are seeing and that would be a faulty brake light switch or the brake light switch is out of adjustment.
Brake Lights Don't Turn OffUsually this issue is caused by an improperly adjusted brake light switch. Sometimes it could be a defective switch, but this is rare.
Check bulbs Fuse Stop light switch
Brake light switch failure, bad ground wire at rear of vehicle or fuze blown.
Check the switch on the brake pedal
the plug behind the battery might be unplugged or that same plug is disconnected from the fuse box
that sounds like i ground in the bake by the lights or if it has a trailer plug i would start their
Alternator has/is going bad.
brake switch ???
Brake bulbs. You might need to replace them. It just happened to mine and it was tricky to do it. To take the brake lights you need to pull them from the sides, there is a small piece that would come out easily and then you can just take the screws out.
replace the break light bulbs?
Try the tractor with a different trailer, the pig tail is most likely not connecting properly.
Most likely no brake lights would be due to a faulty switch on the brake pedal or a bad fuse.
you have bad contact in ground cable of the brake lights You might also like to check that there has not been a bulb replacement lately that uses a single contact in a double contact socket. This would have the effect of shorting the brake and tail light inputs and thus turn on ALL lights when brakes are applied or the parking lights turned on.
Blown fuse or bad brake light switch?
brake light switch would be most common cause
The BOO (Brake On/Off) Switch may need to be replaced. If it is bad, it would cause the brake lights to NOT illuminate when the brake pedal is applied.
check the fuse for the brake lights, they have thier own. also check the brake light switch at the at the top of the brake petal
The Toyota would have more acceleration a= F/m if the mass of the of the Semi Truck is greater than the mass of the Toyota.
BAD BRAKE LIGHT SWITCH AT TOP OF BRAKE PEDAL
Open the back of your Rav4, on both sides of the back from the inside, there will be a plastic cover over where the brake light would be, gently take that off and you can see the brake lights from there. Just twist the harness that the bulb is in and the bulb should just pop out. Good luck.
Any time you have an strange problem with lights it is a poor ground. Your tail lights are back feeding through the brake lights instead of going to ground. I would start by running a jumper wire to the tail light and brake light ground and I would guess the problem would be fixed. You might also want to look at your break light failure indicator. It commonly goes bad in these models.
