MEET ARROWER, the fun and easy sequence blinking LED, running arrow like kit.


Our ARROWER - L10 has many applications; fill your party with running blinking ARROWERS. Mount the ARROWER on your bicycle so you'll be more visible and have a safer ride when signaling. Mount it on a sign as an direction indication. Place ARROWER anywhere youd like to draw attention and a smile. The unique small design will allow you to mount it almost anywhere. Operate it with 9V battery 12V car battery, via four 1.5V batteries, or via one of our battery simulator kits. The alternative uses are endless. Its designed for the beginner as well as the expert. Please drop us a line at and let us know how you use your ARROWERS!


Do It Yourself (DIY) and enjoy your kit.



(9Vbattery and clip are options)


Configure it your way: Arrow or line running LEDs








Simply ignore Q1, LA1 to LA4, RA1 to RA5 while assembling the kit, and get running LEDs in a striate line.


Assemble left to right only the require LEDs in your application i.e 6 LED etc.


Change C1 from 0.1uF to 1uF as well as R1 from 5.1M to 510K-Ohms, and slow down the clock (generated by the IC LM555) therefore slow blinking (running light) speed.

Sequence running light (LEDs) Arrow (9 or 10 LEDs) or line (up to 10 LEDs) shapes





MEET ARROWER Our running blinking arrow like LEDs kit is based on 10 bit counter. Using the LM555 as a clock generator that consequently increase the 10 bit counter by one therefore light the next LED. 


The Arrow shape light together with the last LED. we use additional NPN transistor to push the necessarily extra current require by the additional 4 LEDs. This basic kit can work with many conventional NPN transistors i.e. 2N3904, 2N4401, 2N2222, etc.


The 150 Ohms resistor determines the 4 arrow's LEDs brightness and limits the current flow to about 10 to 15mA when running between 9V to 12 VDC corresponding. 


The ARROWER flash running rate is determined by C1 capacitor and R1 resistor. Increasing C1 while decreasing R1 will slow the rate 


Note: The 9V battery and clip are for demonstration only and is not included in this kit.
