2009-2023 Harley Davidson FLHTCUTG Tri Glide Headlamp Bulb
From 2009 to 2023, the Harley-Davidson FLHTCUTG Tri Glide led the way in trike development with its unmatched style, power, and presence on the road. The clear-cut feature of this machine is its headlamp bulb. It’s more than just a light source; it’s like the beast’s eye, shining in the dark and making sure the way ahead is well-lit. In these 14 years, improvements in lighting technology have turned the simple headlamp bulb into a light source that works well, lasts a long time, and is very bright. The Tri Glide’s light has always been made to improve rider safety while keeping the brand’s signature look, no matter if it uses halogen, LED, or advanced adaptive technologies. This bulb doesn’t just light up the road; it also lets everyone know that the Tri Glide is there, showing that Harley-Davidson is dedicated to combining top-notch usefulness with iconic design.
HEADLAMP
See Figure 61. The headlamp assembly uses replaceable quartz halogen bulb(s).
Refer to Table 13 for bulbs. See a Harley-Davidson dealer or service manual for bulb replacement.
CAUTION
When replacement is required, use only the specified sealed beam unit or bulb, available from a Harley-Davidson dealer. An improper wattage sealed beam or bulb, can cause charging system problems. (00209a)
CAUTION
Never touch the quartz bulb. Fingerprints will etch the glass and decrease bulb life. Grab the bulb with paper or a clean, dry cloth. Failure to do so could result in bulb damage. (00210a)
WARNING
Handle bulb carefully and wear eye protection. Bulb contains gas under pressure, which, if not handled carefully, could cause serious eye injury. (00062b)

WARNING
The automatic-on headlamp feature provides increased visibility of the rider to other motorists. Be sure headlamp is on at all times. Poor visibility of rider to other motorists can result in death or serious injury. (00030b)
NOTE
Vehicles with multiple beam headlamps that are individually aimed should be adjusted so both lamps converge into one pattern.
- Verify that front and rear tire inflation pressures are correct and that suspension is adjusted to the weight of the prin-cipal rider. See SPECIFICATIONS.
- Fill fuel tank or add ballast to equal the weight of the fuel needed.
NOTE
See Figure 62. To aid in properly placing the motorcycle, a perpendicular line (1) can be drawn on the floor. For best results, choose an area with minimum light. - See Figure 62. Draw a vertical line (2) on the wall.
- Position motorcycle so that front axle is meters) from wall.
NOTE
As the weight of the rider will compress the suspension slightly, have a person whose weight is approximately the same as that of the principal rider sit on the motorcycle. - With the vehicle laden and upright, point the front wheel straight forward at wall and measure the distance (4) from the floor to the center of the HIGH BEAM bulb.
- Draw a horizontal line (5) through the vertical line on the wall that is 2.1 in. (53.3 mm) lower than the measured bulb centerline.
