Headlight keeps going out, replaced the bulb - 1984 Honda VT 500 C Shadow

Occasionally bulbs will fail for no reason. Replace the bulb and try again. If it fails again, then you likely have a problem.

Your ignitor and control unit for that headlight is going bad. Replace those with a new bulb and you will be good to go. Its number 4 in the picture.

look inside owners manual in glove compartment look up bulb replacement in the back index it will show and tell you how to replace headlight bulbs. be sure to wear clean gloves, because headlight bulbs or halogen type bulbs, if oil from hands or skin touch the halogen bulb it will cause halogen light bulb overheat and blow out.you can go by auto parts store when you buy new headlight bulb the salesperson will go out to vechicle and replace headlight bulb for you wont charge you any thing.just charge you for the headlight bulb.

Hi there, together with providing you the solution to the problem, I also took the liberty of going one step further in giving you steps on how to remove the headlight bulb.

• Find the hood release handle and activate it, the hood should pop open.
• Once the hood is popped open locate the hood secondary or safety latch and release it. Then finish opening the hood.
• Locate and remove mounting clips for any plastic shields that cover the headlight lens mounting screws or clips.
• Some headlight bulbs can be replaced by simply grasping the bulb socket behind the headlight lens and turn it counter clockwise to remove it. This will expose the headlight bulb.
• If the headlight bulb socket is not accessible the headlight lens may need to be remove or obstructions behind the bulb removed to gain access to the headlight bulb socket.
• To remove the headlight lens remove all mounting screws and clips that hold the headlight lens in place.
• After the headlight housing has been removed from it's mounts, release the headlight bulb from the headlight lens housing (turn counter clockwise) the bulb will then come out of the headlight assembly. Once removed, visually verify that the replacement bulb is exactly the same as the failed bulb before to ensure a proper repair.
• Clean the headlight lens free from all debris to help maintain the seal from the bulb to the lens. This will keep moisture out of the lens.
• Install the new headlight bulb by turning the retainer ring or bulb clockwise.
• Re-install the headlight lens housing and reinstall electrical connector.
• Re-install plastic covers.

After the job is complete turn the ignition key to the "on" position and activate the headlight switch. Observe the newly replaced headlight bulb to ensure proper operation.

Glad to be of help!!!

Assuming you mean the bulbs and not the assembly - yes. Look under the hood in the area where the headlight is and you should see a wiring harness going onto the back of the headlight. The headlight is held in by a lock ring. Remove the wiring connector and take off the lock ring by turning it counter clockwise a fraction of a turn. Coax the bulb out (It is a 9007 bulb available at any parts house) and the installation process is the reverse. It is recommended you replace headlight bulbs in pairs - and keep the old working one as a spare.

sounds like the head light switch may be defective.

I would replace the wires with a lower gauge wire (thus thicker) this may help this issue

When you replace headlights in today's cars, DO NOT TOUCH THE GLASS OF THE BULB!. Handle the bulb only with the packing material the bulb ships in, or with a clean dry cloth.The oils in your skin will cause premature failure of the bulb.

Also, check the sockets (car side) carefully to make sure they are not burned.
