Perfect so far.

Definitely worth seeing about getting it installed by a pro. I did it myself after my local shop quoted me really high. I got it installed, but it took some fair amount of trial and error, along with the better part of a day. The product is a great value for the price, but it came with very little useful directions, which I expected.

As far as the functionality goes, it works like a dream. I only hooked up the headlight part, and it is great. You don't realize how awesome auto-headlights are until they aren't there.

Directed 545T Headlight controller

This product came as expeded, and looked new. Everything was included, and no parts were missing. I installed it fairly quickly, and the instructions were also fairly easy to follow. I have installed alot of electronics in vehicles, and often do custom work. After 1 week of use, one relay inside the unit stopped working, so the headlights didn't come on automatically. I did some rewiring, and got it to work again. After another week, the unit stopped functioning all together. Would be nice if the durabilty was more than 2 weeks.

Inexpensive Luxury

I haven't touched my headlight switch in months. The 545t turns on the headlights as daytime running lights for safety whenever the car is running and turns on my parking lights when it starts to get dark or anytime my wipers are activated.

Works well, relaible, easy to install

This is the 2nd time Ive used the 545T. The first one was installed about 2 years ago in my Range Rover. (That's right. An $80,000 vehicle that comes with no automatic headlights... and no auto climate control!) The 545T has always been relaible. Instructions are clear easy to understand except the almost hidden instruction to cut the red wire inside the unit if you want to disable daytime running lights.

something unique

Most cars have this as a factory equipt item but my car did not have this. I have a 2011 toyota corolla s but i had this installed by a professional installation shop, I also have this install in my 2001 toyota trundra sr5 but it's a good thing to have when going in underpass or tunnels the headlight goes on automatically. I recommend this product to a vehicle that doesn't have this as a factory equipped item.

Does What it Says

Put this in my 1987 Jeep Wrangler & it hooked up easily in my opinion. Works just as advertised. I've been using Directed products since the early '90's, and they've been good to me so far. So I felt good going with them here.

Works great!

I had it installed at BB. The Directed 545T was installed in my 2007 Sportage without any problems or extra charges. It works as expected.

Great value

Had it installed on my wife 2010 Honda civic. It works great. Never have to worry about my wife forgetting her headlights on again. I had it installed by my self but if u don't feel confidence doing your self I guess u have to pay for get it install. Directions are easy to follow n definitely I will recommend this product to my family and friends.
