When it comes to budget lighting, and lots of it I figured I would chime in with my $0.02. I had some cheap round Walmart tractor lights on the front bumper of my truck that worked great for years until we got some Texas sized hail that killed them and every other living creature in the storms path a few years ago. I think I paid $10 per light plus switch, fuse, and some wiring. For under $60 is was an amazing and cheap set up! Like all survivors I knew I would rebuild after the storm.
Having received a promotion from grease monkey mechanic on airplanes to parts guy (and now helicopter pilot) I decided to go with some landing lights. I figured I could get them cheap ($19 each) and make it work.
The big and first problem I faced was getting a housing for them. Harbor freight saved the day. I dropped in and purchased 4 of these bad boys.
I immediately went home and removed the cheap lights from the rubber housings and installed my new landing lights and they fit perfect! So I reinstalled them right where the old lights were.
The next big hurdle I faced was the amount of power these consume, they are 14v 250w lights. My buddy and I determined we would need 10 gauge wire and 20 am relays to make this work. Cheap wire and a single fuse was not going to cut it. So I scavenged some wire from work, bought lots of relays, a fuse block, fuses, and dug up some switches that came off a Cessna Citation 501. You know you're cool when your truck has jet parts, talk about added horse power! I also opted for the jet switches because they are 20 amp circuit breaker switches as a backup if a relay fails, the switch should save my truck from burning down. We ran the lights on two switches, one powering the inner two, the other running the outer two which are slightly angled out.
We managed to get everything installed and working like it should. I am not good at the whichcraft we call wiring and electricity but thanks to a very good friend, having access to parts at the hangar, and a very understanding wife we knocked it out. We started the wiring process around 6 pm and had the lights running by 2 am! We had other projects going on as well, installing and wiring a 3rd battery, power inverter, and fridge. I did make the mistake of doing all this the night before leaving on a +3,000 mile adventure which is why we stayed so late making sure we had it going. I would highly recommend doing any install when you are not pressed for time, and having a friend who knows more about electricity and relays than you do. Do it right the first time, don't just "make it work." Thats what made this all possible.
Three things I was not prepared for after the install. One is the enormous amount of heat these light put off. I would not drive thru a field of tall grass with these on, guaranteed to ruin the field you are in and subsequently your day. They do not get hot enough to melt the rubber housing but they certainly get toasty. When you turn them off the element continues to glow while they cool down for 3-5 seconds. Two, as someone else mentioned, they do turn the night to day and every street sign that reflects anything reminds you of that as you drive by squinting until its behind you. I use them all the time at night and they work great! I only ever switch one set on at a time because they are so bright, you don't need all 4 (unless oncoming traffic decides to high beam you). Lastly I like the cheap light housings, but being rubber mounted to a hard surface they vibrate. I am on the hunt for a plastic or metal housing to eliminate this problem.
Total cost for this budget install was just under $250.
$80 - Lights x4
$35 - Harbor Freight light housings x4
$60 - 20 amp relays x4
$20 - Blue Sea Fuse Block
$60 - Wiring, switches, wire connectors, fuses, and other misc stuff.
On a side note for any install in a fixed housing. Always leave a service loop of wire for when you have the change a bulb out. If you don't leave enough wire to pull the bulb out of the housing to change it you're going to hate life for a simple light change. Also, "they say..." when you install a light with an element spanning the gap of two prongs it is safest to clock the light so the element is going up and down. Reason being for shock resistance, the element it less likely to fail while because it can absorb bouncing around better when in the standing up position vs laying down. I need to re-clock mine. I have had one go out from what appeared to be vibration. Who knows if its true, but it sounds good to me.
All in all I really like my lights, but to be honest when I decide to stop being cheap (or find some for cheap) I do want to upgrade to LED lights. Cooler operation, less power draw, and bouncing down the back roads won't affect them as much. Until then, I love my $20 landing lights. My buddy said at night it looks like a train cruising down the road. Maybe I should invest in some horns...?
Don't worry about always having the latest and greatest, even the big boys upgrade slowly. Notice the LED landing light, but halogen taxi light. Just remember to put your gear down before landing, neither light works well when you're sliding down the runway an night.
