Diode Dynamics SmartTap™ Turn Signal Flasher Relay / DD4015 Fits
6 customer reviews
definitely like this mod quick easy and simple o yeah cheap too add a little fun and dress up to your ride!! I increased my flashers to 6 and it was supper easy to change also use the wig wag strobe looks dope.
Overall well made with one little flaw....
The good: The tap to turn is great! Makes commuting just a little bit easier. The variable flash pattern is wonderful on the road to attract a bit more attention especially if you hit your hazards when coming to a sudden stop on the interstate. The physical module itself has a fit and finish equal to the OE relay. Installation is pretty straight forwards and easy. There is one piece that you have to remove and reuse to hold the relay. It's a flimsy part easily broken or warped so just be careful removing it, you'll need it later. I like having extra approach lighting. My car is a 2015 STI Limited so I already had approach lighting via the head and tail lights. This adds the turn signals so it's just brighter now and looks better. The bad: There is an issue where if you hit the unlock button the turn signals glow for approach lighting but the fob cannot be used to unlock other doors or the trunk until the timer on the turn signal approach lighting expires. So if you miss a double tap to unlock the doors or realize you want to open the trunk after you have unlocked the doors you won't be able to do it until the approach lighting turns off. Also there is a slight pause when you turn on the hazards. It's maybe a second before the hazards start where the OE relay is immediate after pressing the buttons. Both issues for me are not enough for me to remove this relay and replace it with the OE one but they are annoying.
Great idea but the Welcome lighting does not work on 2016 BRZ. To bad one of the better features I was looking forward to especially nice at night in the dark getting into the car.
Bit pricey, but...
I wanted the tap functionality and the welcome lighting is pretty cool too since I have the diode dynamics C-lights. Installing was very easy
Purchased for my '17 WRX, super easy to install and happy with it overall. Watched some videos where some removed it underneath. My body doesn't contort like that anymore, don't be stupid like them. It takes 20 seconds to pop the side panel off and one screw is all it takes to have simple access to the relay. I don't think it even took 5 minutes to remove the stock relay and install the new one.
Plug and play
Very easy to install, doesn't require removing any of the dash of plastic panels. Just move your seat back, unplug the factory relay, plug yours in and go. Would be interested to see how some of the unique hazard flashers work with aftermarket tail lights but otherwise a very cool piece.
