The VTEC spool is 1 amp - loading is up more can damage the transistor
I made a little LED to test this very function - and have installed a similar light in some people's cars too and some also had a two LED function. Funky.
What should be done though is
Variable cam actuator = 1 LED
Cooling Fan = 1 LED
Perfect Engine temperature = 1 LED
Low Coolant = 1 LED
Would be nice - but more look like a Generator control panel.
