I got my resistors installed today in the rears. Sure enough hyperblinking is gone and I am a happy camper. Definitely more room to install resistors in the rear area over the front. I ended up using t-taps with no issues.

Well I ended up going with these

They had a photo that just convinced me to try them out

Hopefully they work in the front WITHOUT adding another resistor or else I'm gonna have to make some magic happen



I didn't want yellow. Just 5k white light. You are able to get red, yellow, and white I believe.
Not to be the bearer of bad news, but white turn signals will be illegal in all 50 states. You may not get pulled over immediately for it, but it won't pass inspection.

Red/Amber are okay for the rear turn signals, but the front turn signals must be amber legally. You can run switchbacks if it's a dual-filament socket, but it's not legal to run single-filament white.

A non-flashing, white running light will be okay though!

How did you guys switch up the front turn signal bulbs to the LEDs?

I checked the manual and it said to change them from the bottom by the tires, take off the fender and go from there..... Seems kinda odd to me.

I've always changed bulbs from under the hood. What did you guys do to change it, and are there any vids out there that you looked at,

Fairly certain it's illegal in Canada as well, but I hope you don't have any issues. It does look good, but that's why switchbacks are a more popular option for turn signals.

Hi, I'm trying to change out my front turn signals. Does anyone have instructions or know how to switch out the bulbs without pulling off the fender liner?

I know the front is a 7444 bulb. But switching to a LED you'd need a resistor?

I hate Splicing the wires and making it look messy,

Is there an ALL WHITE LED you've used that had a resistor already attached?

I've seen them for the rear ( but different bulb size. The rear is a 7440).
These work grear

How did you replace them though? The front gives you very little room to work with and I can't find instructions?

you have to turn your front wheels so you can pull back the fender well a little. It’s not that bad but make sure you take your time and put a piece of electrical tap around the bulb and connector to keep it from detaching after installing the led. It happened and it was sitting inside the lens compartment.

I tried that but can’t get to the turn signal bulb via the wheel well. What year do you have ?

I’m going to attempt to swap my factory Amber front bulbs with aftermarket chrome-dipped bulbs (i don’t care to fool with LED’s and resistors etc) this weekend. I will post an update on what did, and how if i have time. Here’s what i ordered :

https://www.ebay.com/itm/27273495430...mis&media=COPY

I’m hoping they fit. I know our bulbs take 7444 but the eBay listing says it doesn’t fit so i don’t know. Could be a base or something that may be off. Hopefully not but i will update.

Default These worked perfectly without resisters on my 2018
