LED Bulb Conversions

[gunner]

For those that changed to LED Bulbs I am looking for reasonable priced LED bulbs for the #67 standard bulb. The #1141 bulb equivalents are readily available and reasonable priced but I am finding the #67 bulb are priced considerably higher. Where did you find reasonable priced and good quality bulbs for both the #1141 and #67 bulb?

Rather than switch bulbs consider installing LED self adhesive strips in the fixtures. I did my complete 34 ft. trailer, 12 small fixtures, the bathroom valance light, and 3 large fixtures, for less than $15.00.

You can determine the brightness of each fixture depending on how many bulbs you install in a given fixture.

I got all of mine from Dan @LED4 (?) ; he advertises on the forum. He asked what year and model of AS and which lights I wanted to replace. He gave me a $ and number of the bulb. I broke one installing and he replaced it.

I did the complete inside all of the fixtures except the reading lights and outside side marker lights for $88.00. I got them on E bay from China they have been in a year and I have had no problems so far all bulbs worked out of the package.

I have checked them against 1141 bulbs that are selling from $10.00 to $20.00 and can see no difference in quality

Thanks for the replies I will pursue the leads you provided.

How did you make the connection to power? Can you post a picture?

The 67 and 57 bulbs are identical with exception of the glass globe circumference. With the 57 being bigger and the 67 being smaller.

For a low intensity option

For a high intensity option

For the rear license plate light or minimal vertical clearance

I replaced all the bulbs in my coach except the dash warning lights, aux/fog lights, and head lights with LEDs I have many other lessons learned if you need more assistance.

[gunner]

I purchased from Amazon Warm light output for my low intensity and White light output for my high intensity. These will be used for my interior overhead cabinet lights. I should receive them next week and determine if they serve my purpose. I also purchased from Fastenal the upper red and amber LED running lights. Next I will take your suggestions for the Tail and Turn Signal bulbs.

What Bulb did you use for the Turn Signal and what if any problems did you have with them working, did you have to add a resistor?

[Vycan]

Amazon search for "1157 led" then choose one. I did not have to use a resistor on my setup because I swapped out all bulbs. You will find that leds are sensitive to polarity. So if they do not work turn them 180 deg and try again.

Here goes to the strips... Just did all of ours and a few added under the range hood.. Oh my goodness.. What a diff!! We even replaced in the bathroom.. Wife tells me.. "thank you!"

I have installed the LED bulbs in the overhead cabinets, the backup lights and the outside door and flood light and have received but not installed the amber and red outside top lights. I don't understand your advice regarding turning the 1157 equivalent LED bulb 180 degrees since they are used both as a light and separately as a turn signal and the tabs on the body only allow the bulb to be inserted one way.
In my search for equivalent 1157 bulbs I have found non-resistor, build in resistor and comments that you have to add a resistor also based on another Thread here that on some cruise controls LED will not allow the cruise control to work. Getting confusing and makes me wonder if it is easier to not change the turn signal bulbs or which bulb to purchase.
In that regard I believe you are saying by switching all of the bulbs you don't need resistor bulbs or add a resistor am I understanding that correctly?

Gunter, regarding issues with the cruise controls. Some cruise control systems don't work properly when LED bulbs are installed in place of regular incandescent bulbs. I do know on my old 310 we installed LED brake light bulbs and the cruise control worked but not to long after the cruise stopped working. After doing a bunch of googling the only thing I could come up with was some systems don't work with LEDs. I never found anything saying that they could eventually break something in the cruise control but I found it somewhat suspicious. I replaced the cruise control and on recommendation of the manufacturer I added the relay circuit to bypass the LED light issue.

Bottom line is LED brake lights can affect some cruise control systems and possibly not others. On both vehicles I own I've installed the relay to ward off any potential problems

[gunner]

bkahler I believe your 310 is the same as my 345 where there is one bulb that has two circuits for lights and the other for brakes/turn signal can you clarify what you used for that bulb, resistor, non-resister or adding a resistor to each bulb.

Gunter,

The 310 bulbs were changed to LED back in 2007 and I don't remember where they came from. I've not dealt with resistor, non-resistor type bulbs and not sure why there is an issue. The brake/turn light bulbs were probably 1157 type bulbs originally and the tail light bulbs were probably 1156 bulbs.

I would think as long as the LEDs you buy are designed to replace 1157 or 1156 bulbs then there should be no issue other than potential cruise control problems. The reason there is a problem with cruise controls is the cruise control manufacturers in their design took advantage of how the brake light circuit works when used with incandescent (1157) bulbs. With 1157 bulbs there is a resistance to ground where the cruise control is connected and with LEDs there is a different (probably high) resistance to ground. The cruise control used that drop in resistance to know when the brake pedal was being pushed. With LEDs that signal value has changed so the cruise control doesn't know when the pedal is pushed.

That's why I went to the relay method because I can now change to any bulb I want and not worry about the cruise control working or not working.

If I am understanding correctly the cruise control would actuate but when you press the brake pedal to disconnect the cruise control the cruise control would not recognize this and you would have to manually shut off the cruise control to get the motorhome to slow down.

I believe it's pretty much just the opposite effect. When the brake pedal is NOT being pushed there is little or no resistance to ground through the incandescent brake light bulb so the cruise control see's this as a ground and knows the brake pedal is not being pushed. With LED lights there is no filament and the resistance across the LED is higher (compared to an incandescent bulb) so the cruise control doesn't see the ground signal that it needs to activate the cruise mode. In effect the cruise control thinks the brake pedal is always being pushed.

I got this information from an electrical engineer I work with who explained the differences between how LED lights and incandescent lights work in a brake circuit.

Knowing that the cruise control module is looking for a ground signal when the cruise is activated and does not see that ground signal when LEDs are used explains why the cruise controls don't work properly. At least to me anyway!

Gunner the turning of LEDs 180 degrees was for any bulb that is a universal fit. You are correct, the turn signals only fit one way. So if you swap out the bulbs in your clearance lights for the LED equivalent, you will want to turn the lights on and see how many are in the right way.
