Default are LED turn signal lights a direct swap?

I lost my front turn signal lamp assembly, found a new set (clear) on ebay as well as a replacement socket. The price of a set of yellow LEDs are about the same price as regular lights, can I just put in some LEDs directly in place?

One of the auctions was saying how a 50ohm resistor or something like that had to be used to prevent malfunctions.

Here is what i'm looking at buying

2pcs 1157A 3496 Yellow Front Signal 19 LED Light Bulbs | eBay

It'll be a direct swap as far as installing the bulb, but unless you add resistance to the circuit, your signals will blink about as fast as if there were a bulb out.

50ohms seems like a lot of resistance for a turn signal circuit though (especially when the difference is just bulbs). I'm guessing the seller meant 50 milli-ohms.

Yes or No. Depends on the LED.

I did a LED signal swap and it required a replacement LED flasher relay since the bulbs didnt have built in resistors. If the ones you buy have built in ones, you wont need it.

The auction specifies 180 mili amp current draw. Does that sound like it has a built in resistor?

The stock regular bulb draws about 1.75 amps (1750 mili amps), so it's not the same. Like Hobo said, there are replacement blinker relays that are designed for LEDs. Those are not sensitive to current like the stock one is, so it will blink normally even with a low current and there is no need for resistors.
