Bicycle lights can be expensive, theft prone, and illuminate a narrow area.If you're looking where you do, look at the LEDs.You can mount one on a helmet.
Step 1: To modify, choose a bike helmet.
You should already have a bicycle.If you have more than one, use the old one first.The easiest way to use a helmet is with a flattish rear end.
Step 2: Adapt to the helmet with a headlamps.
A lamp that straps onto the user's head is associated with mining.A hinged front light mount is required to direct the beam up and down.The kit should have a rear-mounted battery pack with a bright red rear flasher, a high-power white front light, stretchy coiled wire connecting the parts, and take relatively high capacity.For a long, bright life, LEDs are a necessity.Since you won't use that part anyway, an old one with a dirty or bad strap would be perfect.
Step 3: Pick a glue that will stick them together.
Heavy-duty automotive trim style double-sided tape is convenient to use and fill gaps.Don't run off of curved surfaces with a thick, fast curing variety.It's difficult to find a glue that won't attack helmet materials such as a mix of plastic and foam.Allow the surfaces to dry for a good bond.
Step 4: The strap on the headlamps needs to be removed.
The rear light, battery holder, and associated wires should be removed from the strap.The project won't require a strap.
Step 5: Put the components in a test position.
The main light has to be mounted where it doesn't tilt to one side or the other, it must have an unobstructed path forward and be able to pivot to shine straight ahead.The placement of the battery pack is flexible if the rear light is integrated into the holder.When the holder is fixed, the battery door must be open.When testing components and checking illumination angles, tilt the helmet to face forward as it would be in use, rather than sitting on a table.Excess slack in the cable may be taken up by the position of the front light forward to back along the crown.To avoid stress to the components, the cable should not be kept in tension, as it may pull loose and crooked, and because tolerances help ensure successful construction.
Step 6: The front light should be Mounted.
Attach the front light to the helmet as you determined to be appropriate, ignoring the constraint of placement of the rear battery pack or light.Before you stick down double-sided tape, check its path in a dimly lit room to make sure it's straight ahead.Allow the glue to cure completely before moving on.
Step 7: There is a rear light.
A gentle curve can be built if the helmet does not have a suitable mounting surface.If it has aerodynamic-looking tail ends of spikes at the back that protrude well beyond its overall thickness, you might trim these in a relatively sheltered area to create a small flat mounting area.The components are light and the mounting area is not needed.
Step 8: The front and rear lights need to be turned on.
You can choose power and blink settings.When there is enough light to see, blinking lights front and back are great.
Step 9: Put the helmet on.
Step 10: The front light can be adjusted to your liking.
Enjoy your ride!
