Our original 1991 Starburst Headlight Modulator was ten years before any of the others on the market today. The original size was 3" x 3" x1". It was replaced by our new Double Eagle microprocessor design in 2003 which eliminated all the transistors, resistors and binary counters the others still use today. Our new design is a third of the size and even more reliable than our early models, many of which are still on the road after more than 20 years.

Headlight Modulators are a prime example how we've lowered
prices through advanced technology without sacrificing our quality.

2003 - 2016 Single H4 - $119.95

Dating back as early as the 1980's our original Starlight Driving Light Controller, Firefly Trunk Flasher, Brake Alert, Hot Shot, TailGunner units for the rear signals, SignalGuard and Hazard Flasher have been replaced with our current microprocessor models that include multiple easily selected operating programs allowing it to be tailored to the users riding preferences. The new models range from the Tour Pack Flasher, Freedom Brake Flasher to the Panther 557 BLT units for the rear signals, Turn Signal Cancel and Hazard Flasher. The new models are not only smaller but simpler to install and built to even "higher reliability" standards.

One of the newer designs, Front Running Lights, for the front signals was discontinued in 2015
due to the limited size of the market.
The newer design Hazard Flasher was discontinued after 14 years in 2017 due to changes in
market and falling sales. (59 units in 10 years, 23 in last 5 years)

We introduced the Star-Tron which was the very first trailer and accessory isolator on the market in 1988. It was replaced by our new solid state model in 2003 with the size being substantially reduced from 3½" x 5" to a compact 1½" x 3" so it would fit in the smaller spaces and even under the seat on some of the newer motorcycles. Since most people use it solely for a trailer or side car the new model was designed primarily for that purpose. If accessory isolation is needed it requires a separate unit.

The newer design was discontinued in 2016 as few people today pull a trailer or use a sidecar.



Our Amp-U-Tron digital volt/amp/temp meter was produced between 1992 and 2001 for the Gold Wing 1500. It was a sophisticated and complex device in reading actual current (amperage) and voltage using a remote sensor as is done on jet airplanes so the current doesn't flow through the meter. It also read the ambient temperature which was great for monitoring when black ice could form on the roadway. The manufacturing cost in building our LCD display wasn't a mere few dollars. We sold our unit to the motorcyclist for $200. Nothing of this design type or function was produced by anyone else except in the aviation industry which had a selling price over $1000.00. Due to the change in the Gold Wing riding market at the time, wanting cheap parts and accessories, we decided to discontinue production and a design for the GL1800 in the works was also abandoned. There's not a comparable replacement on the market today or in our current product line. The cheap motorcycle suppliers didn't have the engineering expertise to build a real LCD digital meter. This was one of those cases where riders wanted low prices and wouldn't pay for an outstanding product with great features as well as high quality and ended up with nothing. It's an unfortunate truth.

Sorry, for those who've seen one
of these and call us hoping we might have one sitting on some shelf they really are long gone, 16 years ago.

BMW Can-Bus and Can-Bus/LED modulators have been discontinued due to cost, limited size of the market and slow sales. We came out with these in 2008 and they worked great but couldn't continue to build something that's not supported with adequate sales.

This is about another company that has tried building these type of units.
We found this on a forum.
I (He) bought a xxxxx(brand) modulator for my Can-Bus motorcycle. "It did not work,
so they sent me another. It didn't work either, and they couldn't figure out why, so yet
another was sent. After it didn't work, I gave up on modulating the main headlight, so
they sent me two of the smaller modulators to put on the driving lights. (need to note
this wasn't legal)
They worked great for about 6 months, then quit working. Ah, well.
Money wasted!


After six years we discontinued our Double Eagle Harley 2011- 2017 Can-Bus & Can-Bus/LED modulators for the Ultra, Tri Glide, Road Glide, Street Glide and
Road King due to our cost of manufacturing, maintaining inventory, limited size of the market and market price resistance to paying for this type of device.

The Ultra, Road Glide, Street Glide, H9/H11 Road King and Can-Bus/LED (Daymaker) had to be built on our more costly Double Eagle microprocessor platform to meet NHTSA (d.o.t.) rules for LED bulbs and work without causing Can-Bus operating fault codes.

These type of units cannot be built on the cheaper design platform used by others in the market. Simply put, we couldn't compete with something that doesn't exist at the prices Harley riders were willing to pay.

There have been a few who called and willing to pay for a special build but these are few and far and probably should be refered to as not the ordinary shopper. Very recently one ordered a unit and said he suffered from a left hand turn accicent a couple of years ago and lost his wife. He realized the price of an expensive modulator is still less than the cost of a lost life.



Windows "Constant Current" 2 amp Dual Channel Battery Charger - 1994 - 1997

A "GREEN" charger before it's time.

This charger kept batteries alive for up to seven years and even woke up those long after their apparent death because it had a true operational window. It would force feed a battery which is only accomplished with a true constant current design. It charged two batteries separately for best results and the charger could be powered by a small solar panel in areas where the electrical grid was not available.

Too advanced at the time and $200 couldn't compete with the cheap $30 black box voltage trickle chargers. We completely
overlooked that people don't understand battery chemistry and believed the false claim a trickle charger was constant current
and somehow magic and smart. Our's was a constant current charger and comparable models found today cost around $700.


These items go way back
Starsteps foot rest for GL1200, GL1500 & Yamaha Venture/Royale (also sold to Yamaha Motors)
1987 - 1993
Driving Light Mount for GL1200 and GL1500
1991 - 2000 (stopped with the GL1800)

Our Starsteps offered the greatest comfort for the
passenger because the height was adjustable and
the size provided a good flat surface for foot size. It
also tipped upwards and stowed out of the way.
In 1992 a fellow came up with an idea to build a
foot peg that also stowed but it couldn't compare in
comfort. Of course, he sold it at a lower price. Thus,
we discontinued the Starsteps.

I talked with him, he was a nice fellow, and I quickly
realized he knew nothing about engineering or the art
of manufacturing or foundry work. He had a machine
shop mill every set from aluminum billet. He said he
found it more expensive to build than he first imagined.
In six months time he was out of business. The outcome, riders no longer could find quality foot rests like the Starsteps. It's a recurring story never learned in America.

The high quality metal housing driving lights we sold were the only items not produced by us. They were discontinued in 1999 because the company that built them went out of business due to so many people buying off shore low price over quality. They closed and fired all the workers. The only alternative today is buying lights at an auto parts store made from plastic.
