Good choice

It's easy to install on my Lexus RX300 and it's cool to have strobe and bright feature.

works for 13 Honda Crosstour

I installed these last night to our 2013 Honda Crosstour. I'm in love with how they look and at how bright they appear. They do strobe as indicated and appear to do blink in sync with each other. So far, I've had no issue with codes or hyperflashing of any sort. Time will tell as to how they hold up! For now, I'm incredibly pleased
