Default Another LED bulb question!

I am replacing all the inscandescent bulbs in our 1995 Pleasureway. Found a great deal for White 1156 18-LED Bulb Lights at
http://www.suntekstore.ca/white-1156-18 ... ht.html.ca. as I mentioned in a previous post.
My question is: My incandescent bulbs are #1141. Is the above LED light a compatible replacement for the 1141? Just want to make sure I am ordering the right ones!
Thanks everyone,
Mamello

Yes.

The base of a 1141 and a 1156 bulb is the same. They are different brightness.

1156 bulbs are 26.9 watts. 2.1 amp hr
1141 bulbs are 18.4 watts. 1.44 amp hr

More watts = more current used.

Your new bulbs will only use 105mA. That's roughly 1/10th of what your current bulb draws from your battery.

18 LEDs/bulb??? I think the ones I got last year are only 9 LEDs each.
You'll go blind if you're not careful!!!

right, you will go blind! haha.. where are you ordering your led lights from? is it an internet source or do you see them in person before you purchase?

A good internet place is SuperBrightLEDs. They have an online cross reference chart for
automotive replacement (incandescent to LED) bulbs that's pretty useful. Link.....
http://www.superbrightleds.com/
Prices and shipping costs are reasonable. I just replaced my van's door step and cab dome courtesy lights
with their 4410 festoon LED bulbs and they work GREAT!!! At 1/15 the power consumption, I can leave a
door ajar for a while and hardly drain my vehicle battery at all.

I've noticed a SuperbrightLED (no "s" on the name) website as well, but haven't dealt with them. No idea what
they're all about, but they advertise factory pricing.

Good luck 2u2.

p.s. after some further thought, you can get a touchy feely look at LED bulbs at places like Canadian Tire,
Nutech Electronics (in the Niagara Ontario region), Princess Auto, and some truck stops now carry
them too, although the selection isn't always that great.

update....
I purchased the White 1156 18-LED Bulb Lights from Suntek.ca (service was efficient and prompt) and replaced all 11 #1141 incandescent bulbs in our Pleasure Way. They worked just fine in all the fixtures except in one dual ceiling fixture(one of 3 ). Not sure why. The incandescents work fine but not the LEDs. Anyone have any ideas? If I take the fixture down, what should I be looking for?
And guess what?....When I turned ALL the lights ON...We did NOT go blind!!!
In fact, I wouldn't want anything less than these 18 LED bulbs!
The LEDS do give off a whiter light, a little more like moonlight instead of sunlight! Kinda Kool!

Do the suspect led's work in other fixtures?

If so, I suspect low voltage is the problem. LED's won't light up at all if the voltage is too low. A simple test would be to plug into grid power and see if they work. If you can't plug into grid power then start the van motor and leave it running and test your new led's in that fixture.

Have you verified what lights you actually need to replace the dual fixture incandescents?
Superbrightleds has a link to a Sylvania website where you can determine what bulbs your chassis
needs by their OEM bulb type. My RT is on a 2002 Chevy Express Van chassis, and the Sylvania site
lists all the bulb numbers, by application. I can then go to the S-B-leds page with the cross reference chart
and get the LED equivalent numbers.
I'd have to suggest using the http://www.superbrightleds.com charts and replacement aids, to see if you
can figure it out. Without seeing the fixture, it's hard to guess what might be the problem.
Are the leds single (1156) or double (1157) contacts on the base? Make sure the bases of the leds and
incandescents are the same. Maybe the dual overhead is a dual intensity bulb fixture?
Here's a link to their starting page for figuring out what you need.....
http://www.superbrightleds.com/1157.htm

Good luck, LEDs rock!!!
Glad your eyesight is still OK.

Thanks for all your advice Marko And Mike.
Plugged "Beebop" (as in "bopping along in our B!) into the grid, but it did not make any difference for that light unit, the LEDS still would not work.
The unit that does not "like" the LEDs is one of three identical units. They are typical older RV units...flush with the ceiling...a bulb on each side covered with those plastic snap on covers and the on/off slider switch in the middle. There is a set at the front, in the middle and near the back door.
It is the back door one that does not like the LEDs, only the incandescents. When I took the LEDs out of that unit I tried them in the other 2 units and they worked fine. I also took a very close look at the bases where the bulbs go in and compared them to the other 2 fixtures. The fixtures looked identical.
So now I am just plain puzzled!
Anymore suggestions?

Me stumped. I'd say the low voltage theory is the best one probably, although I'd think it would
take more juice to get an incandescent glowing, than an LED.
Sounds like a trip to the Pleasureway website and ask them a "tech" question, unless any other
PW owners on here have any ideas. Here's a link to their "contact us" page.....
http://www.pleasureway.com/contact_us.php

You might also want to try RVNet for an answer. They're pretty good over there, too.

Must be Polarity. Positive & Negative.

Drop the fixture, reverse the wires and try again.

Unlike incandescent, led's require correct polarity.

Thanks guys ....I will try reversing the polarity first and see what happens. If that doesn't work, I may just leave the incandescents in...and not use that fixture when we are drycamping.
Besides, with 9 new 18 LED bulbs showering our interior with light...another 2 might just make us go BLIND!

I don't think there's a polarity indicator on the festoon bulbs I used in the door and
cab courtesy lights. I just popped them into the clips and they all work fine without
worrying about the polarity.
Coincidence, or is there a difference between the leds in a festoon (fuse-shaped 4410) led
versus an 1141/1156 type of led?

Just curious.

UPDATE>>>Well...reversed the polarities as Marko suggested. No luck. LED bulbs still did not work. So I will just leave in the incandescent bulbs and be frugal with their use. The light unit is right at the back door, so it is not one we use a lot.
Thanks everyone for your advice and suggestions in trying to figure out my LED bulb issue.....really appreciate this forum.
Cheers,
Mamello

Mike - I don't know anything about how the led festoon bulbs work.

Mamello - I'm sorry that you went through that extra work - I thought for sure that the problem must have been polarity. I'd really like to know the answer to this.

"Come, Watson, come!" he cried. "The game is afoot." - Sherlock Holmes.

I love a mystery too. And it drives me nuts when a puzzle like this eludes resolution.
I'm leaning back to the low power theory marko posted a while back.
Could there be some fusing or something which lowers power to the fixture
when it senses a low/no voltage draw (like from a replacement LED)?
I'm trying to think of a reason why you'd want to drop power to the rear overhead fixture
if the bulb wasn't working properly. Fire/spark/short hazard near propane/fuel maybe?
Mamello, have you tried contacting PW and bouncing it off them?

Another thought. Maybe the bulb bases look the same but aren't exactly the same height.
If you put the incandescent bulb beside the LED on a table top bases down, and get down and look
at them from the side, do the little nubs that keep them in place when you press them in and twist,
appear to be the same height off the table top? I had a problem with a back up light in the Chev
tailight assembly and the replacement wasn't quite touching the center contact in the bottom of the
fixture. I had to pull on the little tab inside the base of the fixture with a pair of needle nose pliers
to get the base/tip of the bulb to make a good solid contact with it. Or, you might have to tug the tab
in the base of the receptacles up/out a bit to make contact with the bulb base. Just a thought.

BTW Mark, I picked up a new isolator in Ft. Worth ($124 all in) a week ago, while "passin' through".
Now I have to wait for a dry/warmish day to try to get down under the front end
to try to replace the old one. I wish there was a drive in DIY garage with a pit somewhere
near me.
How's the 'trek (pun intended ) east going?
