When to Replace

• The bulb does not illuminate when power is applied
• Light output is dim, flickering, or inconsistent — indicating filament degradation
• The glass envelope is blackened, cracked, or has visible internal damage
• The bulb base or contact points show corrosion
• Preventive replacement — bulbs have a finite service life and should be replaced on a schedule for safety-critical lighting

Installation

1. Confirm 421-06-26260 in your Komatsu parts catalog
2. Disconnect power before replacing the bulb
3. Remove the old bulb — note the bulb type and connector configuration
4. Handle the new bulb with clean gloves — skin oil on the glass envelope can cause premature failure in halogen bulbs
