Switchback LEDs for turn signals, solution to hyperblink problem!!!

OK, so I am new to the forums, and this is my first post, but had to be done. I was researching everything to get the switchback LEDs for my front turn signals (my rear is LED already on the SX). I have a lease, so I cannot mod my sled too much or there could be issues. I want to outline the options briefly as I think many people are facing this issue.
Switchback LEDs are lights that will fit into the 1157 Optima socket and that will generate bright white light in parking light/DRL mode, and then when the turn signal is activated they will generate flashing amber light. At issue is the fact that LEDs do not have the same electrical impedance as traditional bulbs, and this means there will be a mismatch of the car's circuitry and the LED. This results in "hyperflash", meaning that the light will flash very quickly, which most find annoying and indicative of a low quality car mod. Here are your choices as I have found:
1) Install the Switchback LEDs (about $40 a pair on ebay or other websites), and just sit back and enjoy the seizure inducing hyperblink
2) Install the Switchback LEDs, and also install the load resistors (on on each harness). Load resistors will adjust the electrical impedance so that as far as your car's circuitry is concerned, the LEDs are identical to the bulbs. The way to connect the resistor is to A) cut the wires and splice (messy and possibly voiding some contracts/leases idk), B) use a "t-tap" which is a clip that makes a very small cut in the wire but is very clean and precise compared to actually cutting things up, and C) purchasing an in-line resistor circuit (these are relatively new to the market).
This last option is the reason I made this post. I was really hesitating to use the t-taps and do something that may upset the lease gods, and this last option is very good for those who want "plug and play". I found these on ijdmtoy.com:

This means you can plug it in to your harness, then plug LED into it, and you are all done. I will buy this today and likely get my LEDs from them too to save a little on shipping, plus I heard they are brighter than most.
One note: Load resistors are like brakes for electrons, they slow them down, and just like breaks on cars, they get hot the more they work. If you run your hazards a lot or tend to leave a turn signal on for a long time, be sure to mount these away from anything that might be temperature sensitive. If you can mount them on a steel support or any metal, that will help as a heat sink and draw off the heat, which will protect everything from your car's circuits to the surrounding plastics, etc.
Hope this helps, will update when I get the install done. peace
