Neat little in dash warning for blown bulb
 

I noticed my right green dash turn indicator flashing at double speed the other day. Confused me for a bit, but decided to check outside if there were any problems with the indicators. Behold, blow bulb front right side.

Changed the bulb (not an easy task in a 23 year old car)with much cussing and swearing and sweating plugged it back up and dash turn indicator back at normal speed again.

Neat huh! Not a bad in car monitor for an old girl!

When a bulb burns out, the relay gets more juice, causing it to double time. The side benefit, is that the dash light blinks twice as fast as well.

Yup, I call it the "rice rocket" effect.
