Cruise not working
After a friend told me my '48 Ford's brake lights were hard to see, I replaced the 1157 bulbs with taillight lenses that have 40 LED's embedded in each lens and plug into the 1157 socket. I've got really bright tail and brake lights now,but the cruise stopped working. I've Googled the issue and found that I probably need to install a resistor so the cruise is fooled into thinking the old 1157 bulbs are there. Has anyone tried this and does it work? The car has a Rostra Ultra Cruise II.

Yep, like Jeff sez, you need a load for the cruize module to sense and drop out of cruize control

- makes sense as there are no amps pulling on the led lights to click the relay s in releasing the cruise control Just like when you put in the led's the turn signal will not flash with regular flasher need to use the electronic model

Yes, I've just put cruise in my '37 and there is a note in the instructions about using LED brake lights. I'll look it up later, but it said you would have to install a relay. Here's a note out of the Dakota Digital CRS 3000 instruction manual: Please Note: If you are using L.E.D. taillights please wire a relay as shown here to allow for proper Cruise
Control operation. Use Dakota Digital RLY-1, or any 5 pin SPDT normally open relay.
When using the relay, the Violet must go to Pin 30 (RLY-1 Black) ONLY.
Pin 86 (RLY-1 Red) is the only wire that now goes to the cold side of the brake switch

I suggest that you contact the manufacturer; they seem to support their products:

- I have never heard of that. But I am sure Google has the answer.
