Safety First

• Turn off the power: Either switch off the light or turn off the power from the breaker.
• Let it cool down: Halogen bulbs get extremely hot. Wait at least 10–15 minutes before handling.

Tools You May Need

• Soft cloth or paper towel
• A step ladder (if the light is ceiling-mounted)
• Gloves (optional but recommended to avoid skin oils on the bulb)

Step-by-Step Instructions

1. Locate the Fixture Type

• 2-pin halogen bulbs often come in G4, GY6.35, or G9 formats. Look at the socket or user manual to know the exact type.
• Identify whether the bulb is in an open socket, glass cover, or fixture with clips.

2. Remove the Cover or Shield (if applicable)

• For covered fixtures, gently remove the glass dome or panel.
• Some may require unscrewing or unclipping.

3. Pull Out the Old Bulb

• Hold the base of the bulb (not the glass) and pull it straight out with a gentle but firm tug.
• If it’s stuck, wiggle it slightly. Do not rotate—2-pin bulbs are straight-in, straight-out.

4. Avoid Touching the New Bulb’s Glass

• Use a cloth or gloves to handle the new halogen bulb.
• Skin oils on the glass can cause the bulb to overheat and fail prematurely.

5. Insert the New Bulb

• Align the two pins with the holes and push straight in until it’s snug.
• Don’t force it—if it’s not going in easily, double-check the alignment and bulb type.

6. Replace the Cover (if removed earlier)

7. Turn the Power Back On

• Test the light. If it flickers or doesn’t turn on, check the bulb’s seating or compatibility.

Review: Tips, Pros & Cons of halogen light bulb
