Review on Enhanced Performance Stoplight Switch - Standard Motor Products SLS-342 by Nick Tucker

Such a simple solution to a problem that is killing you! Not having brake lights isn't safe, and in the case of the Elantra, the brake lights were on, so the cars behind me ignored them. The installation is very easy. I won't say it's easy as it's under the dash and hard to get to, but it's not that hard. Apparently this fixed the problem. Be sure to also order the pad that goes to the brake pedal, this switch presses on the pad and the combination of the two elements ensures it works properly. https://www.amazon.com/gp/aw/d/B00FHTTWWIW?psc=1&ref=ppx_pop_mob_b_asin_title
