Daylight Visible Bike Light - Front/Rear Combo - 100 Lumens on 2 AA's

Step 8 Add more parts

add C1 first.

before adding Q1, glue a little plastic insulator onto the proto-board where the tab of Q1 will go. Q1's tab is live, you don't want it accidentally touching something.

then attach Q1, and glue the tab down to the plastic insulator.

if you are using the dimming resistors R3 & R4 you can add those also to pin 2 of Q1.
