Seems like the taillights on the old trucks are mounted very low. That plus the fact that 9 times out of 10 some jerkoff is tailgating you and they are too darn close to notice your taillights. I notice a lot of people are adding a high brake light to their older vehicles.Not making excuses for the jerks who ride around tailgating people,but that seems to be a way of life anymore.And it aint only the younger crowd that do it,I see many silver haired old ladies who can just barely see thru the windshield tailgating.As for brightness there are the new LED taillight replacements.And for you people who are restoring your old bolt to factory specs,this does create a problem.However there comes a time when safety has to rule over originality.
