Thumbs up I converted to LED lighting!

I converted all the lights on my 2005 Civic to LED. LED lighting draws much less power than incandescent lighting, so my MPG should go up a little I didn’t do it strictly for MPG, I also did it to have brighter, longer lasting lights with a more crisp on/off quality too. I think that LED lighting should be added to the list of mods to improve efficiency. I do not know how much gas I am saving, but what I do know is that turning on the headlights no longer bogs down the engine at idle. Less load on the electrical system can only mean increased efficiency. For people running without an alternator, LED lighting will allow you to go farther between charges also. I am very pleased with this upgrade so far. The indicator lights turn on and off so quickly and cleanly, and the headlights are a beautiful white color instead of yellow. They are much brighter too. I will upload pictures of the lighting when I get home. However, I need to change my flasher relay now that I converted to LED turn signals because the LED bulbs draw so little power that the turn signal goes too fast because it thinks that the bulbs are burned out. Anyways, what do you think?

I like LED's, and I did all of them on my old Scion xA - including the headlights.

But, the only time you will notice anything is if you are doing EOC at night. The battery keeps the voltage up longer, with LED's.

It is part of a list of mods for all the reasons you mentioned.

I retrofit all bulbs in vehicles except for the blinkers. They are used so infrequently/intermittently that it's of minor concern, and it allows me to ignore the fast blink problem.

I got my LED headlights for under $40 for the set.

Nice upgrade! I've wanted to go LED on everything on pretty much every car I've had... I just never get to it.

Care to A - B - A test? Just kidding.

That is definitely a better deal. Please make a garage entry for your car. Do you have any instrumentation? There must be some way of pulling actual data to test current draw, engine RPMs with each headlight, something!

I have a Scanguage. I would measure idle RPM, but the RPM would be the same with both bulbs because the IACV would just bring the idle back up. However, according to the Amazon page, this set of bulbs draws 72 watts, compared to standard halogen 9006 bulbs that draw 110 watts for the pair. Also, the stock tail lights draw 70 watts for the pair of large and small bulbs, compared to 10 watts for the pair of LEDs. The front stock front parking lights draw 40 watts for the pair, compared to 6 for the LEDs. So the stock lighting system draws 220W, compared to 88W for the LEDs, a 132 watt savings over stock! If the alternator is 50% efficient, a total of 264W would be saved, about 1/3 of a horsepower! I know that this isn't the kind of data you were looking for, but it's what I got.
