How to Illuminate a Wheelchair for Safety Using EL Wire & LED Strip
I always found that those safety lights for bicyclists on the market were never good enough when riding in the dark. That got me thinking about people who use wheelchairs and how unsafe the night could be when they want to go out. So here's what I came up with:
I decked out this ordinary wheelchair with EL wire on the spokes and LED lights underneath the seat. The LED light is incredibly bright, so I put that underneath the seat and it gives the whole wheelchair a luminescent glow that looks really cool at night. You'd definitely be hard to miss with a ride like this at night.

- 2 25' El Wire + 3V Inverter
- 2 10' El Wire + 3V Inverter
- LED Light
- 1 Wire Cutter
- 1 Plier
- Masking Tape
- 28 Gauge Galvanized Wire
- Clear Zip Ties
- 4 AA Batteries
- Binder Clips
- 2 Two-way Splitter Connectors
For this particular design, each wheel has 1 25' Sky Blue EL Wire shaped like an "X" in the center of the wheel and also outlines once along the circumference of the wheel's tire. On top of this Sky Blue wire is another "X" design, but used with a 10' Blue EL wire and this does not run along the wheel's tire. The last design is used with a LED Light strip, which outlines the bottom of the seat, giving the whole wheelchair a luminescent glow. Feel free to use your own EL wire colors and designs!
A. Decide what the desired pattern will be. If needed, sketch out the design and create a number sequenced diagram of each defining movement.
B. Use your EL Wire to help guide you in creating your pattern.
C. For this particular pattern, use masking tape to secure the EL wire down as you progress through your design.
A. Beginning with the 25' Sky Blue EL wire, secure its inverter inside the spoke of the wheel with either tape or zip ties. This allows the user to easily turn the power on just by dropping his/her hands down to the sides of the chair.
B. Begin following the number sequenced diagram while pulling tightly to keep the shape sharp.
C. Once the first sky blue X design is completed in the wheel, the wire should end where it started, which is near the inverter.
The wire should end where the wire began, which is near the inverter.
A. Now, continue using the rest of the 25' Sky Blue wire to outline the plastic rim of the wheel. As the wire moves along the tire, frequently tape the wire down to keep the form secure and maintain its circular shape.
B. Do not cut excess wire yet.
Now that the basic shape is there for the first Sky Blue X design, use galvanized wire to securely place the wire onto the tire without the tape.
A. Cut roughly 2.5" of galvanized wire.
B. Wrap the galvanized wire around the EL wire once and twist the ends with a needle nose plier until the 2 ends are tight and straight.
C. Use a wire cuter to cut the galvanized wire ends until about 2-3 cm is left.
D. Stick the twisted galvanized wire between the plastic rim and the rubberized tire with your finger.
E. Remove tape as you complete each section around the tire.
F. Repeat steps A-E to circulate the entire tire.
G. Once the end of the 25' Sky Blue EL wire reaches full circle, snip off the rest of the wire with a wire cutter and pin down the remaining wire with galvanized wire again to secure the end.
Your final product should be complete, as there will be no more modifications for the Sky Blue wire.
A. Remove the inverter from the 10' EL wire. It will not be needed because there will be a two way split cable to avoid the chunkiness of having two inverters on each wheel.
B. Using the 10' Blue wire, attach the inverter connector to the two way split connector and tape it down to the wheel.
C. Just like before, follow the numbered sequence for your second X numbered diagram.
Important Note: Whenever this wire intersects with the first 25' wire when crossing, always put the 10' wire behind the pattern of the initial 25' wire. This will help keep the form and shape of both the wires. Pull tightly.
D. After the second X is completed in the center of the wheel, take the end of the wire and loop it around an area that will keep its X shape. Pull tightly.
E. The 10' Blue EL wire will not hold itself in the loop, so use either galvanized wire or a zip tie to secure the looped areas together.
F. Snip off any remaining EL wire with a wire cutter.
Repeat all steps to the other wheel of the chair.
The insides of the wheels should have loose connector wires.
A. Secure these connector cables by gathering the cables in a thin strip.
B. Use pliers to twist the galvanized wire connector cables together.
C. Cut off excess galvanized wire.
D. Stick the twisted galvanized wire in between the rubber tire and plastic rim.
E. Repeat steps until the rest of the inverter cable wires are neatly hidden from view.
A. Using the LED wire, map out the desired outline of the chair with the LED light.
B. Once decided, clean the area the adhesive will attach to with rubbing alcohol or water.
C. Secure the LED light with clamps or clips to the desired outline.
D. Start peeling the sticky strip from the bottom of the LED light.
E. With the sticky side exposed, push the LED strip onto the underside of the chair.
F. Remove the clamps or clips as the sticky tape is being peeled.
G. Continue steps until you reach the end of the LED strip.
Packaging LED strip components-
H. Connect all the LED components together.
I. Put all the components into the EZ-EL velcro bag.
I. Place the entire bag into the back pocket of the seat.
Now that all the EL wires are in place, test out the wheelchair with everything powered on.
Make sure that the inverter on both sides do not collide with the chair when wheels are spinning.
If any of the EL wires at the intersections are loose, use galvanized wire to secure them into place.
