1157 2 prong LED bulb for use in vehicles◦ Bulb uses 20 white 1210 SMD LEDs and 34 yellow
1210 SMD LEDs.◦ White LED is significantly brighter than the yellow.◦ Yellow LED array in bulb consumes 0.103 A and
white consumes 0.093 A◦ Load resistor to trick vehicle hardware.
Application

LED bulbs purchased do not operate as planned
Add onto the simple switchback circuit by adding a capacitor
Size components properly to keep the white light from turning back on while yellow is flashing.
Figure out which side of wiring to install load resistor.
Problem Statement
