I had an '89 Accord and could hear the difference in airflow with the lights popped up.

It's worth mentioning that the mpg hit from the pop up lights up also includes the additional electrical load. So it won't translate exactly to a 4 mpg savings by going to the flush mounts - but it's going to be better than before.

Nice work!

Thanks for the compliments. I am going to start working nights. I will post the difference in night vs day mileage next week.

Nice work!
The power being used by the lamps does eat up some power/HP,
but even if the lights weren't on, I could still feel the heavy drag on my 1991 Laser RS when I hit the Flip-up button.

And, when I was zooming along with them already flipped up, and switched on the power to the lamps,
I really didn't feel much of a drag, if any at all..

What is 200W translated into HP?

What many folks don't understand is that those "low" beams are actually low/high beams with dual filaments. Thus, while your "low" beam headlights were on with the highs, they were on high beam, not low beam. The headlights you installed and many new headlights only have a single filament per headlight.

Dang!! Seems like those rap guys with the 800 watt subwoofers are wasting
a considerable amount of gas while annoying everyone in the neighborhood..

Heck, the power going to my high beams could power an E-Bike for miles!!

I know this thread is old, but I'm sure since it's linked on the mods thread, people see it, and this quote, which is not wholly correct.

Dual filament bulbs turn off one filament in favor of the other, so only one at a time is on. If they were wired correctly, both could be used, but the heat would destroy them quickly. This is most common with sealed beam single-headlight (per side) designs.

Now, Look at EF/ED Honda Civics (These I know for sure). They're Two-bulb composites (per side).

When you turn the headlights to low beam, the low beams come on. When you turn the headlights to hi-beam, the lows stay on, and the highs come on. Thus, 4 headlight setup, all working at the same time. These bulbs are 9005/9006, by the way, so they're not dual filament bulbs.

While one could argue that this is inefficient, removing the wiring and such to stop this action, and make only the highs come on when the highs are on, and only have the lows on when it's the selection, would ultimately be a waste of time. The physical energy would be better spent utilizing some other method than attempting to gain .1 HP of efficiency loss.

Verdict: Wiring all four headlights to work at the same time in tandem while in hi-beam mode is safer due to added lighted area, and saying that it's a waste of efficiency is simply splitting hairs to find a reason to say someone else was wrong.

BTW, OP, nice job on the hood... looks spiffy as a clean unit. Don't forget to remove the motors and frames under those buckets... extra weight

I need to do this to mine. How long did this take to do?
Four more mpg, would be nice. I would bet side mirrors are costing us the same mileage as lights.
