Why annoy other drivers during daylight hours. If they cannot see an object
as large and unique shaped as a GMC motor home coming towards them, then
one has to question why they are still in possession of a drivers license.
I personally hate DRLs. But, it is America after all. Spend your money how
it pleases you.

Renewing wiring on a 1977 23 ft Birchaven

Thinking of all exterior lighting to LED except headlights and adding DRL

Plan - replace flasher ( only one on this coach) with a electronic one
LEDs will be non polarity sensitive
Install a DRL-1
Include out side upper clearance light in parallel with side
clearance light on front
Wire rear upper clearance light and side light as the front is
wired - front is wired
Turn on - side off
Turn off - side on

Hoped for result
Engine on all running lights on

Turn signal on
Directional light flash
Side clearance lights flash
Top out board clearance light flash

Will this work? Jim

10-4 James...with the DRLs coming at me when I'm turning on to the highway I can't see the motorcycles that are ahead of the cars that have the lights on.

Jim and Terry,

I understand what both of you are saying, and this is all part of an argument that the motorcycle people had years ago when states started to require us to run with the headlight on. (This was in spite of the fact that studies done in at least two of those states showed that this have no effect on motorcycle safety.) I put it in the same box as having the landing/taxing lights on when in the landing pattern. It helps others to know whether you are coming or going.

But then, on the streets, highways and byways, we have other issues.
One is that about 40% of the drivers (being generous) on the road are idiots and have no clue what s/he should be doing.
Maintenance can be dirty, takes technological tools (like a screwdriver) and is too expensive. So things like headlight alignment are just not done. Having out of alignment headlights on is very common in states that have no required vehicle inspection that includes this. Michigan is a great example here.

I am going to put some LED strip lights in my grill during my winter work and couple them as DRL (actual method not yet determined) in the (possibly fruitless) hope that it will intimidate some bozo from port tacking (a racing sailors term for trying to take right of way he does not have) us Again. They seem to think that the coach is either slow because it is big, or maybe farther away because it is a smaller front than other coaches. I really don't know. I do know that I am tired of dealing with it.

Side Note:
You think it is bad out there now, wait until autonomous braking is common. I expect that to do just about what the automatic transmission did.

Matt

Whenever I'm riding my bike, I ASSUME the drivers entering the roadway do not see me, and prepare for them to pull out right in front of me AFTER my safe reaction space is already used up. Those pre-intersection thoughts have saved me several times even though my headlight and front turn signal lights were on. Unfortunately, twice in the past few months I have heard the tires squeal BEHIND me as inattentive (or blind) drivers have slid to a stop behind me when I was already stopped for traffic, and one actually (fortunately) saw me in the last 25 feet and ran off the road to the right to avoid crushing me in between her car and the one I was stopped behind. She was putting her cell phone down as I looked over at her. The DRLs on her car were not helping either of us at that point, but they were on. A collision warning system in her car might have snapped her back to the task at hand at that time, much like the teacher slapping the yardstick on the desk when half the class was on the verge of falling asleep. Autonomous braking would probably have seen the vehicle in front of me, but I don't know if it would have detected me on the motorcycle 12-15 feet behind it. Might still have gotten crushed.

I believe the autonomous braking and lane-drifting systems that are being introduced now are going to lure our younger drivers into a false sense of robotic control of the vehicle that THEY are supposed to be controlling. Even the Toyota commercial shows the girl lost in the reverie of singing a song and only the lane-alert system snaps her back to reality and saves the oncoming vehicle. Other commercials seem to give a pass on inattentive driving, showing how the vehicle will save them when they stop DRIVING a moving vehicle. Autopilot in the air with long range radar is OK until you get within range of the airport, where there is much more activity, which is also more tightly controlled than transportation methods on the planet's surface. There is just too much independent activity down here on the ground for an automatic system to compensate for 100% of the time. If they manage to stop you from 60mph in time for an obstacle in the roadway, what about the vehicle behind you? 60mph is 88 feet per second, and very few, if any, can stop that quickly. That's why we have to have drivers that can process the information and change lanes or take to the weeds if necessary. Can't do that if your not paying attention.

DRLs are not going to help any of this and actually constitute another distraction and take away from the alert status of the flashing lights of emergency vehicles, making them harder to distinguish from the sea of moving lights.

On the other hand, maybe we should require flashing beacons and audible alerts on ALL moving vehicles, like the earliest regulations for motorized vehicles on city streets over a hundred years ago Laughing I am personally guilty of this by having the rub rail on the GMC lighted by LEDs when the parking lights are on, and they flash opposite the turn signals when they are flashing and the parking lights are also on, depending on whether I switch the ground for them to the marker lights or a constant ground. Either way, they are currently only on when the parking lights are on.

The Non-Polarity style LED assemblies are available for most applications.

see this catalog
http://luxormarine-rv.com/LuxOr_Digest.pdf

I would suggest that any application that has an LED light assembly have the correct polarity anyway! If you put a polarity sensitive in the wrong socket then it is your fault if you haven’t checked the wiring anyway.

So I guess those have a protected automatic inverter circuit built into them? Great! That will be a big help for some of the reverse wired fixtures in the GMC and perhaps some boats too. So now I can use LEDs to replace the floor lighting in the GMC without replacing the sockets. Didn't see any LED strips yet, but they might be in there somewhere. Thanks JR!

You don't HAVE to replace the sockets. Just cut and resplice the socket wires to correct the wiring error. Use crimp type butt splices and you won't even shorten the reach of the existing wires.

You could make your own polarity independent LED lamp with four LEDs and a resistor, two of the LEDs would be lit at any given time. Just wire them like a diode bridge (AKA bridge rectifier) with the LEDs being the diodes and the "load" replaced with the current limiting resistor.

I always knew I could reverse the wiring, but when I went looking for LED replacements for bulbs 2 years ago (maybe 3 now), I couldn't find LED replacements for that #67 bulb in those floor lights (which are really license plate lights for truck bumpers), and the same story for the clearance lights on top. Kinda gave up on that idea and just got some colored bulbs for the clearance lights and didn't really use the floor lights anyway. Glad there are some people still looking for that stuff and sharing the knowledge on the list/forum so I can renew my enthusiasm for the LED substitutes and reduce the current drain in both systems. Back then, I had found substitutes for the #194 bulbs and used them in the instrument panel and in the low-voltage lighting out in the yard. They work well, and really brightened up the gauges, but don't dim very much in the instrument panel before they cut off, and the ones outside in the yard are just starting to fail after 3 years of use at 4 to 6 hours per day.

Good suggestion on the bridge circuit for double polarity, then when 2 of the diodes fail you can reverse the bulb if it is a T-10 type socket and get another life out of it!

Almost 10 years ago, I wanted both RED and LED bulbs for our floor lights. What I found were expensive. So, I bought red LED trailer clearance lights. They have been great and particularly good for locating the black dog in the dark.

If autonomous braking can detect motorcycles at stoplights and intersections then it could save a few lives every year during Bike Week in Daytona.

During WWII allied aircraft approaching land in daylight learned that DRL's would actually reduce the range at which they could be seen by the enemy.
