Blinker Genie and Blinker Genie 2: Run and Turn From a Single Bulb

The Blinker Genie lets a single-intensity bulb work as both a running light and a turn signal by powering the lamp through the running-light circuit and blinking it off during the signal pulse. Motorcycles use the Blinker Genie; cars and trucks with switchable running-light circuits use the Blinker Genie 2. Covers the two-product split, the universal versus pre-wired R1/R6/Diavel kits, the expected post-install hyperflash and its relay or load-equalizer cure, mounting, and brand-specific wiring notes.

Magic Strobes Brake Light Flasher: The 10 Patterns Explained

The Magic Strobes Brake Light Flasher adds a programmable flash-then-solid pattern to the brake light you already have, no integrated tail light required. It has ten selectable patterns, works on cars and motorcycles, and runs on either LED or incandescent brake lights. This guide explains what each pattern does, how to pick one, and what you need on your bike or car for it to work. Intended for off-road use only.

Universal Smart Triple Play: Run, Brake, and Turn From Your OEM Tail Light

The Universal Smart Triple Play is a controller-only module that lets your two rear turn signals work as running light, brake light, and turn signal at the same time, without replacing your OEM tail light. It works with LED or incandescent lights, supports bikes with or without a center tail light, and has a built-in 10-pattern brake modulator. Off-road use only.

No Flasher Relay to Replace? LED Turn Signals on CAN-bus and Computer-Controlled Motorcycles

CAN-bus motorcycles monitor each lighting circuit by expected current draw, so LEDs can trigger a bulb-out or lamp-failure warning even when they work. This guide explains why CAN-bus flags LEDs, keeps the CAN-bus bulb-out problem distinct from flasher-relay hyperflash, names the bikes that fight back hardest (BMW, Ducati, late-model Honda sportbikes, Harley/Victory/Indian), and covers what works: CAN-bus compatible Blaster-X tail lights and kits with built-in load equalizers, plus standalone load equalizers. Products are off-road use only.

Stealth Plate Mount vs. Traditional Fender Eliminator: Trade-offs

Two ways to ditch the bulky OEM rear fender, compared: a traditional fender-eliminator look that keeps the plate visible on a tail tidy, versus a stealth plate mount that relocates the plate under the seat for the cleanest tail. Covers what the Custom LED Ultimate Stealth bracket includes (per bike), why it pairs with a Blaster-X tail light, and how the CanBus plate light avoids dash error codes. For off-road use only.

Clear vs. Smoked Lenses: The Brightness Trade-off

Clear lenses are always the brightest, because any tint absorbs some of the light passing through it. We started offering a lightly smoked lens on select Blaster-X tail lights only after they got bright enough to spare a little output for the look, and we never make dark tints. Here is how to decide between clear and smoke on your bike.

LED Headlight Bulbs: Bases, Bezels, and Bikes

Choosing an LED headlight bulb is about two things: matching your stock bulb's base code, and confirming the corded fan and driver will clear the back of your housing. This guide decodes the base names (9005/HB3/H10, H11/H8/H9/H16JP, H7, H4 and more), explains why the right base does not always mean a clean fit, breaks down the fan-cooled design and real-output lumen specs, and covers the headlight bulb-out warning fix. Sold for off-road use.

OEM Turn Signal Connectors and Y-Splitters: Picking the Right One

How to choose between OEM turn signal connectors and Y-splitters: match by the physical plug shape and wire count, not just the brand. Covers the 2-wire vs 3-wire distinction, why Type numbers matter, when a Y-splitter adds a second set of signals, and how to install them. For off-road use only.
