1. It is probably against the law.
2. It might make people think you are slowing down or that your riding your brakes or that your brake switch on your pedal is messed up.
3. Coming from the world of riding motorcycles, choppers to be more specific, lighting is an especially important safety feature. I am ALWAYS of the mindset that the best, most effective brake light is the one that wasn't there before. In other words the one that wasn't lit before you pressed the brake pedal. I would rather have a single running light on my bike and have 2 more light up when I press the brakes as opposed to having 3 running lights that get brighter. The odds of someone rear ending you while in motion are slim compared to when you are slowing down or stopped in my opinion. Evidently the NHTSA agree with me because you can bet if they thought it would reduce the number of rear end collisions they would force the manufacturers to make the HMSLs into parking lights as well.
My 3 cents.. lol
It's your truck, do whatever makes you happy.
on my hyhoe the stop lamps are always lit as soon as you take your foot off the gas peddle...
Regen..
it would be nice to MOD the lower lights to turn on with another switch added to the brake peddle. to light up the lower portion as well.. LED would be required to save power
(it has a separate Independent turn signal circuit on the Hyhoe no running lights)
The goofball above me speaks the truth. I notice a few MPG increase when I run the good stuff, 89 even. It also doesn't knock when I'm romping on it.
I use 91 Octane Cheveron or Shell V-Power
6MPG increase, lowered my cost per-mile highway..
0.14¢ per mile @ $3.75/gallon 91 octane
0.17¢ per miles @ $3.55/gallon 87 octane
I only used 6 gallons for 152 miles. 11.43 L/100km
while the same trip with 87 octane used 7.5 gallons
VVT kicked in yo...
