Introduction
The Portland Design Works Light Nug is an accessory designed to provide an alternative mounting point for bicycle lights. It allows you to attach standard bicycle headlights or taillights to existing eyelets on your bike's frame or fork, thereby freeing up handlebar or seatpost space and offering flexible light positioning.

Setup
This section details the steps for installing your Light Nug.
Included Components:
- 1 x Light Nug
- 1 x Mounting Bolt
- 2 x Washers
Required Tools:
- 4mm Allen Wrench (not included)
Installation Steps:
- Identify Mounting Location: The Light Nug is designed to mount to any standard eyelet on your bicycle's fork or frame. Common locations include fork dropouts, mid-blade fork mounts, or rear frame eyelets.
- Assemble the Mount: Insert the provided bolt through one washer, then through the Light Nug, and finally through the second washer.
- Attach to Bicycle: Align the assembled Light Nug with an available eyelet on your bicycle. Thread the bolt into the eyelet. Ensure both washers are properly seated between the Light Nug and the bicycle frame/fork.
- Secure Tightening: Using a 4mm Allen wrench, tighten the bolt securely. It is crucial to tighten the bolt firmly to prevent the Light Nug from rotating once a light is mounted.
- Mount Your Light: Once the Light Nug is installed, you can attach any standard bicycle headlight or taillight to it, treating the Light Nug like a section of handlebar.

Operating
The Light Nug allows for flexible placement of your bicycle lights. You can mount lights on the front fork, rear frame, or even on compatible racks or baskets that feature standard eyelets. This versatility helps to free up handlebar space and ensures your light beam is not obstructed by bags or other accessories, providing optimal visibility and safety.

Maintenance
To ensure the longevity and proper function of your Light Nug, follow these maintenance guidelines:
- Regular Inspection: Periodically inspect the Light Nug and its mounting bolt for tightness. Vibrations from riding can cause fasteners to loosen over time.
- Cleaning: Clean the Light Nug with a damp cloth as needed. Avoid using abrasive cleaners or harsh chemicals, which could damage the finish.
- Material Durability: The Light Nug is constructed from durable metal and is rated IP67 for water resistance, meaning it is protected against dust and can withstand immersion in water up to 1 meter for 30 minutes. However, proper care will extend its lifespan.
Troubleshooting
- Light Rotates After Mounting: If your bicycle light rotates or shifts on the Light Nug, ensure the mounting bolt securing the Light Nug to the bicycle eyelet is sufficiently tightened. The knurled surface of the Light Nug is designed to grip the light's clamp, but a loose primary bolt will allow rotation.
- Difficulty Threading Bolt: If you encounter difficulty threading the mounting bolt into the eyelet, check for cross-threading. Ensure the bolt is aligned correctly with the eyelet before attempting to tighten it. Do not force the bolt.
