Changed all the exterior lights to LED's 2 years ago...Tail/Stop/Turn Signal, and all amber and red running lights...have had absolutely no problems with them and they are brighter than the incandescent lights that I took off, and no troubles with the flasher...the old lenses (only 2 years old) were getting cloudy and falling apart from weather exposure...if I had to do it over, I'd do it again in a heartbeat.
Mine looked good for the first couple of years but now every year I am enjoying replacing at least one LED module. I am now to the point that I am thinking about can opening those lousy modules a rebuild them THE RIGHT WAY (lowering the current draw) and with better LEDs.
After the first Tail light module bought the farm while traveling I now carry AT LEAST TWO of those modules so I can replace while on the road. Buy them each and they are nearly $50 each or as I wised up just buy another tail light "pair" of modules for about $60.
Spent $7 per marker and now I have 4 markers which are only lighting on half of the marker..
As far as the flasher goes, most vehicles now days use a separate set of fused circuits which use a set of relays FOR THE TRAILER LIGHT CONNECTION. The vehicle in this case DOES NOT see any load change.
HOWEVER if you decide to put LED bulbs in your VEHICLE tail lights you WILL need to add the load resistors. Modern day vehicles use the body control computer to detect the proper bulb current. If it doesn't see the correct current drawn it IS supposed to hyper flash..
Keep in mind HYPER FLASH is if you replace the vehicle incadescent bulbs with LED lights.. - riggspExplorerChanged all the exterior lights to LED's 2 years ago...Tail/Stop/Turn Signal, and all amber and red running lights...have had absolutely no problems with them and they are brighter than the incandescent lights that I took off, and no troubles with the flasher...the old lenses (only 2 years old) were getting cloudy and falling apart from weather exposure...if I had to do it over, I'd do it again in a heartbeat.

I have the Bargman #84 LEDs which lpxguy posted.. THEY DO NOT "LAST"
Best I have gotten out of them before they quit is TWO YEARS and that is only traveling 2K miles per year..
I got smart and started buying the two module fixture since it IS cheaper than buying a SINGLE "replacement" module.
I regret the day I ever decided to replace the incadescent fixtures, they were dead simple AND cheap to fix ($1 bulb and contact cleaner once every few years).
As far as commercial truck brands goes.. I replaced all the markers with Grote and guess what? Yep, I have TWO intermittent ones that half the LEDs inside quit every once and a while and TWO that have only ONE of the two sets of LEDs still working.. Yep, that there is gonna cost me a cool $20 for more LED markers vs $4 for four incadescent marker bulbs :S :M
You are only fooling yourself if you really think those commercial LEDs last a long time.. My daily commute is an hr each way on very busy trucking routes.. I work near a major Postal bulk mail center on top of that.. I see hundreds of trucks a week and I RARELY EVER see trucks which DON'T have partial or fully burned out LEDs...
I won't recommend folks to change over to them unless they love spending a lot of money constantly replacing expensive modules every few years.. Incadescent bulbs are dirt cheap, LED modules are not..
Yeah, well I'm sorry for your luck and I'm not trying to be an jerk, but I never heard of Bargman 'till I started fooling with RV's - that right there tells me they are likely cheap junk parts and I would never buy them thinking it was an upgrade / expect them to last.
And seeing trucks on the road and working on them for living are different situations. Those trucks you see with burned out diodes could have a half million miles on them. They also may get covered by a warranty, depending on the brand and the deal the supporting fleet shop has on them. I have heard some talk of exactly that situation you pointed out is positive - a few diodes can burn out and you still have light within DOT spec's whereas an incandescent just burns completely out.
I also have yet to experience an LED short and cause a backfeed that makes all the lights on a unit go wacky the way I have with incandescent.....although, I do enjoy those situations when the customer calls in freaking out thinking his whole rig needs to be rewired because of a broken filament making every light glow when he steps on the brakes - I look like a god when I tell them to pull the brake light bulbs out and replace them and they call back with "That fixed it!!! HOW DID YOU KNOW!!!??".....
And I'm not saying I would recommend someone to change either. You are correct, there is no serious NEED for LED's on a travel trailer, but they DO look nicer and standout better in most peoples view so I would not tell someone NOT to switch if they feel like it.....heck if we are gonna tell each other what to do and this or that is a waste or too expensive then we all should permanently park these RV's/5er's/ TT's and not spend a dime on the excess fuel and campground fees and on and on....it's a hobby, there will be bumps and mistakes and parts that don't work out for us after spending money - learn from it, do what works for you (sound like you are), and enjoy it! - GdetrailerExplorer III

Incadescent bulbs are dirt cheap, LED modules are not.. - Heavy_Metal_DocExplorerSome vehicle mfr's are doing separate circuits for trailer wiring and / or using electronic flash controllers that don't care about the resistance of incandescent or LED bulbs on the trailer circuits.
Sure, it will will give a fault indication when a bulb is out on the TV, but it won't tell you about the trailer because there are to many variables there for them to set the system to proper resistance sensitivity.
Connect up a different trailer with a different number of lights and the flash rate would change. This used to happen on old resistance flashers when you spliced trailer lights directly into the tail lights of the TV.
The newer vehicle circuitry is also why it is not uncommon to have all lights working on the TV and nothing on the trailer plug - separate circuits with their own fuses.

Umm.. the "computer" is designed to detect the current draw of the bulbs as a SAFETY FEATURE to let the driver know when an IMPORTANT BULB is no longer working.
If the computer does not "see" enough amperage drawn it WILL go into hyperflash mode.
Hence the reason one would have to add a resistor when changing incadescent to LED on a vehicle. The resistor SIMULATES the filament of a bulb by WASTING current as heat..
Pretty much a DOT thing.
There is really no good reason to change from the factory incadescent bulb to a LED other than wasting your money AND you will have to defeat a safety item to do that anyways (LEDS DO FAIL, if you don't believe me I HAVE a failed set of $60 Bargman trailer tail lights laying around).
You factory incadescent vehicle tail lights are plenty bright and the bulbs have a long life (I have a 11 yr old vehicle with 200,000 miles on it with ALL the ORIGINAL incadescent bulbs). - RCMAN46ExplorerWith your 2012 3500 Silverado you will not have a problem with the flash rate.

- DHDBExplorerYou might want to check out Bargman and see if they make a dirct replacement for your current taillight.

Just be careful if you live in a state with vehicle inspections since the vast majority of LED replacement bulbs and even a lot of LED assemblies are not DOT approved and might result in a failed vehicle inspection depending on your particular state vehicle inspection requirements.

are you looking to replace the TV or 5er tail lights?
here are the ones I did my 5er with, stock flasher no problems.Moderator edit to re-size picture to forum limit of 640px maximum width.
