LED Blue Headlights

inquire about articleprint articlefeatured articlesupdatesrequest-article

An LED light installed within each headlight housing results in an optical effect, which illuminates the entire headlights blue. The addition to the headlight does not replace existing headlight bulbs, and will not affect normal headlight operation. Each LED light emits photometric energy directly into the headlight housing. The headlight housing contains highly reflective interior surfaces, which dissipate this energy and produce the optical effect. Since the vehicle's headlights produce a greater amount of energy, the blue headlights optical effect produced by the LEDs becomes unapparent while the headlights are in use. Additionally, sunlight will overcome the LED's optical effects. As a result, the custom LED lighting effects are visible at nighttime while the vehicle's headlights are not in use.

LED Lights

Available color options include blue headlights, green, dark green, white, red, orange, yellow, purple, pink, black light, four-color flasher, and seven-color flasher. Both four and seven-color flashers contain LED lights that feature self-contained microprocessors. This eliminates the need for an external controller. Since the LED lamps cannot comminute, left and right blue headlights will present a unique color sequence. The four-color flasher presents a rapid routine containing red, blue, green, and yellow. Seven-color models present a combination routine, slow fading to fast switching. Colors include red, blue, green, white, yellow, purple, and aqua.

Construction of Blue Headlights

Each 5mm LED lamp contains a cylindrical aluminum casing, which covers the LED's rear surface and protects the solder joints within. An adhesive compound bonds the aluminum casing to several layers of protective shrink-tube insulation both solder joints. A rubber grommet located in direct proximity to each casing can slide freely along the wiring. When inserted into the grommets, plastic push plugs create an airtight seal protecting the headlight housings from moisture. The grounding connector consists of an axial-lead resistor soldered directly to a metallic spade connector. A segment of vinyl tubing, encapsulated by shrink-tube, insulates the resistor the rear portion of the spade connector.


All dimensions for blue head lights may contain some tolerance. Overall length, accounting for LED emitter and cylindrical casing, is 0.625 inch. The cylindrical casing features a 0.232 inch diameter. Rubber mounting grommets measure 0.344 inch in diameter and fit a 0.25 inch hole. Grommet height is 0.188 inch and features a slot width of 0.063 inch. The grounding connector measures 1.44 inch in length and features a 0.188 inch diameter. The spade connector measures 0.375 inch in width.


Raise the vehicle's hood and carefully examine the top portion of the headlight housings to check for composition. Determine whether the top portions consist of plastic or glass. Some headlights may utilize a glass lens; however, the housing will consist of plastic. If the top portion of the housing is plastic, locate safe drilling locations allowing adequate distance from the headlight bulbs. Produce a 0.25" hole penetrating through all layers of the headlight housings. During drilling, dust particles may enter the headlight housing, but should dissipate over time. Install each LED emitter through each hole and slightly into the headlight housings. Do not allow the LED to penetrate too far, where the wires become visible while looking in through the front of the headlight housing. Insert the rubber grommet half way into the hole and reposition the LED if necessary. Seal the small hole in the center of the grommet using a sealant compound or the plastic push plugs included. Finally, route and connect both power and grounding wires. Refer to LED blue headlights installation guide for additional details.


Blue headlights consist of a simple series circuit containing two LEDs, resistor, wiring, and ground connector. The current-limiting resistor located within the grounding connector provides a simple but effective method of current limiting. Do not remove the current limiting resistor, as excluding this resistor would lead to catastrophic LED failure. Wiring is pre-assembled, and consists of a 42 inch power wire, 66 inch center wire, and 18 inch ground wire. All wiring is tinned copper, multi-stranded, and contains a standard PVC insulation. After installing both LED emitters, connect the 18 inch ground wire by fastening the grounding connector beneath a screw or bolt located within reach of the wire. To test your ground connection, simply touch the power wire directly to the positive battery terminal. If the ground connection is secure, both LEDs should illuminate.

Electrical Specifications

A typical car battery can provide power to operate an LED circuit for more than several months before visual dimming becomes apparent. Blue headlight power consumption is so minimal, that the LED circuit can remain on for extended period without depleting battery levels. Since the vehicle's alternator charges the battery while the engine is running, the LED circuit should never deplete its power source. For this reason, a power switch is not required.

Voltage Ratings

Loading and alternator activity can cause voltage variations. While the vehicle's engine is running, the alternator supplies current and continuously charges the battery. This typically increases the voltage. LED blue headlights do not feature a voltage regulator. However, the headlight accents can operate within a voltage range up to 13.8 volts DC. Headlight accents may appear slightly brighter while operating at increased voltages.

Current Requirements

LED blue headlights operate from the power provided by the vehicle's battery. At 13.8 volts, typical current draw is 0.02 amperes. This applies to all InGaN technologies (blue, white, green, and purple). For AlInGaP technologies (red, orange, and yellow), typical current draw is 0.03 amperes, at 13.8 volts. When the vehicle's engine is off, current should decrease slightly due to reduced voltage.
