J 25300-D Headlamp Aiming Kit
Properly aim the headlamps in order to obtain the maximum road illumination and safety of the headlamp system. Proper aiming of the halogen headlamps is very important. Due to the increased range and power of halogen lamps, slight variations from the recommended aiming may be hazardous to approaching motorists. Composite headlamps do not require aiming if only replacing the bulb.
When inspecting or adjusting the headlamp aim, observe the following conditions:
| • | Ensure the vehicle is on a level surface. |
| • | Inflate all of the tires to the specified pressure. |
| Refer to the tire placard located on the rear of the left-door frame for tire pressure specifications. |
| • | Inspect vehicles that tow a trailer or carry an unusual load under the same conditions. |
| • | Clean the headlamps before aiming. |
| • | Follow the state requirements for headlamp aiming. |
The J 25300-D is designed to accommodate all composite and sealed beam headlamps in any standard shape or size and in any configuration. Use the adapters provided in kits for different lamp shapes and sizes. Regardless of the configuration, aim the headlamps in pairs.
