Review on Zento Deals 8 Pieces of 6 Ohm 50W Load Resistors – Eliminate Flickering LED Turn Signal Lights, License Plate Lights, and DRL by Brad Ward

This helps eliminate the hyper firmware. but they get quite hot especially when you use them in combination with tail light and turn signals. I ran 2 of these in parallel just for the parking lights and they were still way too warm for my liking, I really didn't want to risk setting my car on fire. Also, you're still using the same if not MORE power to drive LEDs with resistors. I took them off and spent the extra money on a rotary relay. Don't skimp on the relay, buy a Diode Dynamics SmartTap, or better yet, buy the original TapTurn, support the creator of the original! I've heard that the original TapTurn works better and has more features, but I have yet to learn. I did a bit of digging to find TapTurn, but SmartTap is on Prime. $60 is a small price to pay to get it right. Most Subaru vehicles will require a cf18 type relay, but do your research first.
