I was reading about LED conversions,,, and by golly, In the chat box this a/m Jack and Russ was talking about some issues. SMTA.
LED seems the way to go as the standard incondecent light seems to be fading away like the old 8 track players. Several articles bring up a resistance issue,, LED's having less resistance then the old single and double filament bulbs. Some companies sell a top dollar *fix all for this problem, Its a fancy square box that really doesnt fit anywhere easily, requiring hours and hours of frustration and tuck,shove push and cram.
The ole RV guy down the road here said simple solution to a resistance problem with LED's can be found at radio shack or more easily online, Its a simple inline #10 circuit resistor. no bigger then a grain of rice,, BUT you do have to solder it on the HOT lead to the light.The wire your soldering to is no bigger then a push pin so you will be working with very small wire. He tore apart one of those fancy square boxes that *fix all,,, and inside was,,,,,, a number #10 inline resistor with 18 guage wire already soldered to it and therefore gives you larger wire to connect to. He disclosed that fancy *fix all box costs $29.99 and that little resistor only cost $1.12 .
Manufacturers have failed to disclose on many of their products the resistance issue,,, so check carefully, and see if the LED' bulbs or assemblies have a *built in resistor,, saving you a frustrating headache. I did get a laugh when he said Toyota makes the top of the list with full LED change over,,, with the fastest blinking turn signal,, almost like a strobe light.
LED's on clearance lights dont seem to pose a problem,, its the lights that have intermintent breaks in the circuit,, i,e, turn signals.
Hope this little tid bit of info helps,,, and was just passing it along.
