diy cheap asian style car underbody lights

Step 5 Testing

now its time to test what u've made so far. connect the led strips to any 12-14v source. then stick the capactior in parallel with the led strips. all the leds should light up when connected and slowly fade out when you disconnect from the source (leaving the capactiors conencted with the leds).

if it does not work. check polarity of the led. and check supply voltage to see if its enough.

note that if u apply too much voltage. the leds might blow and u have to repair the led strip.
