I've never had a problem with the lights on my toad. They work exactly as they're supposed to.
As Lewster pointed out, the problem could be with the umbilical cable or the seven-pin connector on the Interstate.
It could also be a problem with the (probably six-pin) connector on the Jeep.
There are two generally accepted ways to wire a toad's lights to work through the umbilical. I don't know which was used on your Jeep.
1 - Drill the taillight housings to install separate bulbs wired to the umbilical. The separate bulb would be a dual-filament type that can work for both brake and turn signals. This eliminates the need for blocking diodes because the lights are completely independent of the Jeep's own lighting.
2 - Install blocking diodes in the existing Jeep wiring and then wire from the (probably six-pin) umbilical connector on the Jeep's front bumper to the blocking diodes. This allows the signal from the umbilical to control the existing Jeep lights without back-feeding the signals through the Jeep's electrical system.
Another thing to consider, if the problem affects the brake lights, does it also affect the brakes themselves? I ask because my Roadmaster Invisibrake system in my toad uses the signal from the brake lights to activate the toad's power brakes— the brake pedal in any motor vehicle is hooked up so the brake lights come on slightly before the vehicle's brakes do. If the brake light signal wasn't working properly on the toad, the toad's brakes wouldn't work either. But that may be unique to the Invisibrake, which doesn't require a separate brake controller in the tow vehicle.
