trail tech dial-a-brightness AC voltage regulator
trail tech voltage regulator




trail tech AC voltage regulator! use it on 6 or 12v

* improved AC regulator with adjustable output.
* universal voltage regulator limits voltage to 6.0-16.0 volts for AC systems (DC systems require a regulator/rectifier.)
* conditions circuit to eliminate electrical spikes, protect from lamp blow-outs, and reduce flicker and dimming.
* “dial-a-brightness" for halogen and quartz lights:
* at 14+ VAC setting, the lamps will approach HID lumens (~70%) but lamp life is short (good for racing.) ~25 hour lamp life.
* at standard setting, about 13.8 VAC, the lamps should last about 500 hours.
* at minimum setting, the lamps are not as bright as HID (~30%), but last over 1,000 hours.
* included in trail tech plug-and-play high-output AC electrical systems with model-specific connectors; no cutting or splicing required.
* designed and manufactured by trail tech.

3 of 5 Voltage Regulator February 24, 2022
taco eater : Adam Rogers from versailles, KY United States  
only two wires, no connectors included, the adjustable part has been covered so as to prevent me from adjusting. What the hell do, splice into the yellow wire to headlight and other to ground?

5 of 5 Works as expected July 1, 2019
taco eater : Jonah Loshnowsky from Peru, IN United States  
Spliced in another wire on the yellow one, because the tomos a35 has a 3 prong regulator, then soldered on some connectors. Everything worked great, although i never messed with the adjustable voltage screw. if it ever claps out ill rewrite my review, maybe.

5 of 5 Nice June 3, 2019
taco eater : marc silverstein from bell canyon, CA United States  
Works great.  For those of you that want to run a battery in order to eliminate lights dimming at idle, use a heavy diode in line to the battery.   You will need to change the horn to a DC horn.

5 of 5 Reliable AC regulator August 2, 2018
taco eater : Robbit the Hipper from Hobbitland in Upper Mopedizia  
Use this on any non-stock Hobbit to dump AC voltage above the dialed-in setting. Factory setting of 13.8 is fine, especially if rectifying after the regulator for LEDs or other DC accessories.
