Do these Putco LED bulbs have built-in resisters or do in-line resisters need to be installed prior to use?

You need to buy separate resistors. I bought the putco ceramic ones with these. You need one per side. Keep in kind these LEDs are less bright than stock, but give the LED look(instant on off).

Yes, they are 12 volt resistance bulbs. But they are not real bright to begin with.

Hello,all you need to do is find you bulb code, and you can usually find LED's of that code. So no they are plug'n play.Thanks,Clint

Jeff, the lights are plug and play. Installed them last weekend. Remove old bulbs and replace with wired connector. Install twilight housing as you would the original. Just Insure black wires line up with black wires and all will work. All necessary resistors are already installed. Good luck.

They have an anti flicker resistor just plug n play. But thw customer service sucks the worst. I had to keep on them to refund my money. Due to an issue with moisture inside the housing of the lights.

NO, these LED lights do not need a resistor at 12V. Smart cars (??) with lamp-out detector will need a shunt resistor across the light socket to fool the system into believing it has an incandescent bulb installed. The LED doesn't need the resistor, the stupid car does.

They say not to but I don't understand why. I know that they are taller than a standard bulb so they sometimes won't fit. Led gives off less heat than a standard bulb. If the light you are installing this in isn't run at least 20hours a week you won't really have much savings vs a cfl

Yes. I had CFLs in until I received the LEDs I ordered, and they seemed to work just fine. Perhaps a little dim, but that may have been the bulb, since the LEDs are bright.

No they do not have the LED strip, they are simply just aftermarket housings that your existing bulbs go in to. Simply plug and play. Hope this helped!Mason

Have simply used standard par 38 incandescent bulbs in all 3 units...no problems. Have not tried LED's. JET

I used these, 50W 6Ohm LED Load Resistors for LED Turn Signal Lights or LED License Plate Lights (Fix Hyper Flash, Warning Cancellor) http://www.amazon.com/gp/product/B004EDF8HY/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 by XKGLOW

All led blink faster if u don't like that yes u have to install resistors .I never have problems with blinking faster.

This is a single fillament style bulb. Does not require resistors. You only need resistors when a dual filament is used for flashers / blinkers.

Yes Greg, they wire right up, only options you lose on these is the underside entrance/alarm lights (if you have that option) and the auto dim/tint (if you have that option) I didn't give a crap cuz they look so deadly. No issues whatsoever except the levelling issue which can be remedied with spacers and adjusting the tightness of the bolts. Buy me dude. You won't regret it. Only had me a couple months now but they seem real decent quality...which totally surprised me for the $$$. Good luck!

These bulbs are not sealed like the standard bulb (having a glass cover all around). If you use these LED's, they will need to be in a protective lens cover that is water tight. Also, you may want to use dielectric grease on the socket area to prevent corrosion.

If you don't mind brightness varying or burning out a digital output or a power supply when the LED fails, then don't use a resistor. It doesn't matter which lead of the LED the resistor is connected to.

I don't know if they do, but so far I have not had any issues with the bulbs- they are still the same from my original order, none needed to be replaced yet......
