Primetime is correct. There are NO trunk gate tail lights unless you have rear fog lamps. The brake light that glows brighter in the event of extremely heavy braking, ie, when anti-lock is activated, would also occur on the normal tail lights (those in the corners). On a normal rear light housing, there are two bulbs for rear lightings (not counting the blinker). When the lights are turned on, both upper and lower bulbs would lit. When you apply normal braking, only the bottom bulb would glows brighter. When you apply extreme braking, the top bulb would also glows brighter in addition to the bottom bulb.
