Car Head Lamp Fader Circuit (Breathing Effect Generator)

Last Updated on May 16, 2026 by Swagatam 6 Comments

carheadlightmodifiedcircuit

The proposed circuit of a modified car head lamp fader, “breather” circuit generates a slow flashing effect over the head lamps every time the lamps are switched OFF. The “breathing effect” continues for a certain predetermined period after which the process automatically shuts off. The circuit was requested by Mr. Ray. Technical Specifications I just wanted to say that […]
