Thanks Si; I will look forward to those pics.
The H4 LED replacement head light bulbs arrived yesterday, & I couldn't wait until it got dark, to swap one out in the KE30, & see what the difference was. At a bit over $ 30 for a pair, it is only an experiment, & if it turns out alright, I might purchase another pair, & fit these to my Wife's Corolla or Echo.
The first thing I noticed, was the very tiny plastic electric fan, at the back end of the assembly, to "keep it cool". They are tiny, & my first thought was, "I wonder how long they will last".
As the fan is positioned, where the cable harness, would normally plug in, they provide an integral plug & lead.
The Existing H4 headlight bulbs I had installed, were 100/90 W models, so they were already pretty bright; but I really wanted that "cool white" LED light, rather than the yellowish light, from a tungsten fillament standard bulb.
Changing just one bulb, allowed me to directly compare the light outputs of both bulbs, at the same time.
The result was brilliant, & the pic below, doesn't really illustrate how much better the LED bulb is.
So I'll pop the battery out today, so I can get at the LHS bulb; & take it for a run tonight, out somewhere, where there are no street lights.
Then, I'll start looking at "LED-anizing", all the other parking, stop & indicator lamps.
