HEAVY DUTY RELAY &

HEADLIGHT WIRING HARNESS UPGRADE 

At Aspire Auto Accessories, we manufacture and carry our own Heavy Duty Headlight Wiring & Relay Harness upgrades 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 that utilize the low beam or high beam headlamps at a reduced intensity for illumination. 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 LOW BEAM or HIGH BEAM 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!

 

HEAVY DUTY HEADLIGHT WIRING  & RELAY HARNESS UPGRADE FEATURES

 


•Get a brighter high beam and low beam by connecting your bulbs CLOSER and DIRECTLY to your battery!

•Smart and Heavy Duty harnesses are MADE IN THE USA!

•This harness is 100% Plug and Play and plugs directly into your existing head lamp wiring.

• 14 Gauge or 12 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.

 

• Uses the factory head light signal wiring to trigger TWO heavy duty 40A water resistance relays.

 

•The Dual relays can power bulbs to more than 400 watts.

 

•Designed to endure HIGH temperatures for added protection when running high wattage bulbs .

• Control Module is fully encapsulated for waterproofing and vibration resistance. (Smart Harness)

 

• Anti-Corrosive Lead-Plated terminals for long life and good contact.


• Wires are encased in split loom tubing for protection.

• Fuse Protected with water resistant fuse holders.

• Three (3) Year Warranty

 

There are two reasons to use an  Aspire  Headlight Harness

REASON #1

 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:

REASON #2

Another great benefit of using a Heavy Duty Headlight Wiring and Relay Harness Upgrade 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 our Aspire Smart and Heavy Duty Headlight Wiring and Relay Harness Upgrade:

In simplified terms, the Heavy Duty Headlight Wiring and Relay Harness Upgrade 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 Heavy Duty Headlight Wiring and Relay Harness Upgrade Harness. The RELAYS then CONNECT the HEAD LIGHTS DIRECTLY to BATTERY through 14 Gauge wires. In simplified terms, the Heavy Duty Headlight Wiring and Relay Harness Upgrade is triggered by the head light switch and when triggered, the harness supplies power to the head lights through a more efficient path.
