Headlight bulb problems - LED makes it an easy fix!

Posted by on

Trouble with auto electrical systems is common and more so in light bulbs. Incandescent bulbs are known to fuse and getting pulled over for a defunct headlight of tail light is a common experience. Why do bulbs fuse? It’s the filament that burns out whenever there’s a sudden surge in current, right? We then try our hand at modification by adding extra relays or something similar in the hope of getting better life out of the bulb. When we need to replace the bulb, we do so by ourselves.

Well, we try out all these methods with half knowledge. How many of us know that halogen light bulbs are not supposed to be touched by human hands? That’s because the skin secretions react with the surface causing the bulb to fuse as soon as it ignites. Halogen headlights produce a significant amount of heat, therefore even smallest deposits of skin moisture on the bulb during replacement can affect their performance. The long and the short of it is that incandescent bulbs are delicate, consume more energy and produce far less light than Xenon of HID lights or LED lights.

High-intensity discharge (HID) lights or Xenon lights are brighter than halogens and produce far less heat, but the light emitted is too bright and harmful to oncoming drivers. Light Emitting Diodes or LED lights although less bright than Xenon have more advantages over all other light forms. They have no filament. They transfer current through a semi-conductor generating significantly less heat offering better durability.

Operating temperature of these lights if maintained within limits, they could even run indefinitely. Upgrading to LED headlights isn’t rocket science. Correct information would facilitate the LED conversion of the beams of your car. Some useful instructions relating installation and special adaptors help greatly. With the various types of bulbs, sockets, holders, heat dissipation methods, housings or canbus modules it could get kinda complex. Just follow the simple steps as given below.

Remove your existing halogen bulbs. The back of the assembly will have either a plastic or rubber dust cover which needs to be a twisted to unlock, loosen and remove. Unplug the power cable. Simply twist the globe, mostly counter-clockwise, and pull towards the engine bay.

Disconnect the CANBUS/driver and install the LED Globe into the housing. Twist to secure / clip any brackets that you have unhooked to remove the old bulbs. Copper Heads have copper tails that will need to be maneuvered into the housing to make sure that the dust cap can be put back on securely and retain a water tight seal. Most housing units will have a pre-drilled slot in the dust cap for wiring to run from the globe to the power supply. You would need to check if the driver & canbus, that’s in case you require the additional canbus module, fits inside the unit.

If not you would need to run the driver/canbus on the outside of the housing. Drill two holes. One to run the cable and one to return the wiring back to the power source. Rubber grommets come handy in such cases to hold a water tight seal around the wiring. Once done, plug it back together. Test the headlamps. They have to work. SEALIGHT LEDs make it easy to upgrade. Enjoy the experience!
