Budget Light Mount for Auxiliary Safety Light(s)

You cannot have too many lights. Here is a low-cost way to mount (one or more) “Knog-style” blinky lights on the front or rear of your bicycle.

CAUTION – The “Knog-style” blinky lights should not be your primary nighttime lights – front or rear. They are appropriate for supplemental visibility lighting or as “day-time running lights.”

Here is what you will need:

• M5 bolt (any head style will do – these instructions use a hex-drive head)
• One flat and one locking washer to fit M5 bolt/screw
• 4mm hex wrench (or other depending on the bolt’s head style)
• Electric drill with bits
• Hack saw (or similar)
• File and/or 80-grit sandpaper
• Ruler
• Thread locker (optional)
• Knog-style lights (red for rear, white for front)
• 7/8-inch diameter RX/pill bottle – hopefully in a color that suits that of your bicycle (discard the cap)

Here are the steps:

• Mark and cut the pill bottle to 1.5 inch in length
• Smooth the cut edge with file and/or sandpaper
• Mark the center of the bottle’s bottom
• Drill a small pilot hole in the center
• Enlarge the hole for a snug fit for the M5 bolt
• Thread the bolt through the bottle’s bottom
• Place the washers on the bolt so they are between the bottle and the bicycle frame
• Place a drop of thread locker on the bolt or braze-on threads
• Mount the bottle to a convenient braze-on or to a fender or rack mount – any place that will accept a M5 bolt.
• Install the appropriate “Knog-style” blinky light and adjust so that it is visible from the rear (or front)

If this is too stressful, you can always shell out $22.00 – 24.00 for a Paul Gino light mount – another top quality product from Paul Component Engineering.

While you are at it, replace the batteries in all your non-chargeable lights and then adjust them to they are also visible. A light with weak batteries or low charge that points down or to the side or is obstructed by straps or folds in pack-mounted bags or your riding gear is next to worthless.
