Well, I decided to change all bulbs into the taillight, because they are old now. From time to time I got a brake lamp failure light into the triangle display.
I had these new sensrs in stop and changed them , but I find out that the sensors on my NSX are different, because I only have 2 brake light bulbs, 1 at each side. Something special on old models (KG). Good that I have some spares too. I decided to install them not at the back side of the taillights, I do install them outside. So I can change them without removing the taillights.
