HD RELAY HEADLIGHT HARNESS
At Aspire Auto Accessories, we manufacture and carry our own Heavy Duty Relay Harnesses that fit a wide selection of bulbs commonly found in most vehicles. We have the world's ONLY line of SMART Headlight Relay Harnesses that are fully compatible with factory daytime running light (DRL) systems used in the USA and Canada! Normal harnesses may cause you to violate the law because they require you to disable your DRL's to have them run at full intensity. Note: Disabling DRL's in areas where they are NOT required by law (many places in US), may still have serious legal consequences if you are involved in an accident (ie: disabled "safety" feature).
Our SMART harnesses have our custom CONTROL MODULE that recognizes when the vehicle has DRL on and allows the DRL signals to the headlights to be retained. When you turn on your full intensity headlights, the CONTROL MODULE lets the harness function like all others - which is to connect the headlight bulbs to FULL BATTERY VOLTAGE for MAXIMUM BRIGHTNESS!
Insist on genuine Brite Box Smart & Heavy Duty Harness products by Aspire when you want the best built, most innovative products!
BRITE BOX SMART HARNESS & HEAVY DUTY RELAY HARNESS FEATURES:
• Smart & Heavy Duty harnesses are MADE IN THE USA!
• 100% Plug and Play Installation.
• 14 Gauge Headlight Wires - Our wire is USA made. Don't settle for import wire! Import wire typically has extra thick insulation that makes the copper "under gauge"! Additionally, most import wire we see has very poor quality copper.
• 30 / 40 Amp Relays.
• Control Module is fully encapsulated for waterproofing and vibration resistance. (Smart Harness)
• Wires are encased in split loom tubing for protection.
• Fuse Protected with water resistant fuse holders.
• One Year Warranty
HEADLIGHT HARNESS FEATURES
There are two reasons to use a Harness
To minimize the VOLTAGE DROP in factory headlight systems. Voltage drop lowers the energy delivered to your headlight filaments which reduces their output. Voltage drop is a result of electrical power being run for long distances through thin wires. You can visualize voltage drop by imagining yourself drinking a beverage through a long thin straw (electric energy is the "beverage" and the wire is the "straw"). Examine how the flow of power (red arrows) in a typical vehicle headlight system starves the headlights of power:
Using a Brite Box Harness is that it reduces the current that is handled by the head light switch by a large margin. This reduction in current greatly increases the life of your head light switch.
POWER flows from BATTERY to HEAD LIGHT SWITCH in passenger compartment. When head light switch is turned on, POWER flows back out into engine compartment and then illuminates HEAD LIGHTS. Notice the long distance that power must travel. To make matters worse, typical factory headlight wires are 18 Gauge or LESS. These long runs of thin wires starve your head lights of energy.
FACTORY HEADLIGHT SYSTEM
ADDING A HEADLIGHT HARNESS
Increases the power delivered to your head lights by minimizing the distance power must flow from battery to head lights AND by passing this power through thick, 14 Gauge USA made wire (Smaller Gauge = THICKER wire) with the highest quality copper conductor. Examine the improved flow of power with the addition of a Brite Box Smart Harness:
In simplified terms, the Brite Box harness is triggered by the head light switch and when triggered, the harness supplies power to the head lights through a more efficient path.
HEADLIGHT OPERATION WITH A HARNESS
POWER flows from BATTERY to HEAD LIGHT SWITCH in passenger compartment. When head light switch is turned on, POWER flows back out into engine compartment and then ACTIVATES RELAYS on Brite Box Harness. The RELAYS then CONNECT the HEAD LIGHTS DIRECTLY to BATTERY through 14 Gauge wires. In simplified terms, the Brite Box harness is triggered by the head light switch and when triggered, the harness supplies power to the head lights through a more efficient path.
