Alla Lighting 7443 7444NA T20 LED Switchback Xtremely Super Bright Dual Color White Yellow (Amber) High Power 2835 28-SMD LED Bulbs for Replacing Turn signal Light Lamps (7443)

The Alla switch back LED lightbulbs installing were easy and it works good on 2007 Dodge Ram 1500 with aftermarket headlights. I made sure them work correctly with turn on engine before put them in headlights units. Brightness is good and nice white and turn to amber then back to white. It takes less than a second for switching color but I don't think it's big problem. My old switch back last long years so I give shot to this.

Nice and bright easy install

I am sure this will not apply to everyone which is why I did leave a 5 star rating as the product is exactly as described and function as stated. HOWEVER, on to my specific application... I have a 2016 Chevy Colorado and rerouted the DRL circuit to power the parking lamps to take the strain off of my expensive head light bulbs (and because at the end of the day I like the look better of DRL's on crisp bright white parking lamps.) The down side to this application is that these Alla lights glitch off-white-amber then back to off-white-amber with only the DRL power coming in (half power than normal headlight operation.) They work great once the turn signal comes on and ZERO glitching at night when the Automatic light sensor kicks on the headlights and everything back goes back to normal power output. IF YOU are in the same situation as me it is worth every penny for Diode Dynamics brand switch backs they are more expensive but they work for MY modified application 110%. I tried these because some water got into one of the DD lights and corroded a connection, Long story short I'm positive my situation is unique or very few people will experience the same outcome. Just some quick info for anyone else trying my DRL relocate application. THIS PRODUCT WORKS as advertised and I have kept the pair as back up in case my new set of switch backs go down again. Thanks again Alla lighting!

I bought these a while ago back in early 2018 for my 2016 mustang gt premium. They worked great until I took them out for the opt7 sequential turn signals. Well I popped them back in because I had the opt7 sequential turn signals fail on me multiple times and I’m done not having a unreliable turn signal. And well sure enough when I popped these bad boys back in after sitting in the stock turn signal housing for over a year they work like they should. And they match the tri bar why better than the opt7 6000k. These are like a 4300k-5000k light temp. I’ll never buy anything from opt7 ever again. Horrible customer service and they wanted me to pay for shipping for the return and then on top of it all wanted me to pay for the new set up front and if they deem they are warranty worth they will issue a refund weeks from now. They are in the trash where they belong. I’m Done dealing with them. If you’re on the market for something different from stock get these. They are cheep, bright as hell “brighter than the opt7” and reliable from what I can tell. Plus one day shipping if not same depending on your area. Only good thing I got out of the opt7 was the resistor so my interior turn signal won’t sound like a running horse when trying to turn. At first years ago it didn’t bother me but months later it got real annoying so using the opt7 resistor on the stock wire harness worked great and the turn signal is normal.
