I just replaced the bulbs using both Ebay and domestic sources. All have been performing flawlessly over the last 3 camping seasons using a fraction of the current of the incandescents they replaced. Thus far, the only difference of note between China and domestic sourced LEDs is price as they all were manufactured in Asia. The LEDs I used do not contain onboard voltage regulators so audio/video interference issues are non-existent, and they have easily handled our converter's 14.8 Vdc bulk charging routine.
Beware, not all Ebay sources offer the same quality, reading up on prior LED posts for recommended sources would prove fruitful. I've done many mods to our rig, but preferring dry-camping and boondocking has elevated this mod as one of my favorites. It effectively felt like we had added an extra battery after the conversion.
