There's always one....A good mix of reviews & opinions. Undoubtedly gives good cause for consideration, as too for George in terms of ways the product could potentially be refined as it evolves- user feedback is the best kid of feedback after all.
Maybe I've been unlucky, but I have to wholly disagree with this. Not only have I been booked twice in the space of 3yrs for obscured brake & signalling lights as a result of a towball rack, but I've also been victim to almost running up the arse of a car loaded 4 deep with bikes on a towball rack (admittedly the douchebag driver decided to throw the anchors out & peel off the road very late) as a result of their indicators & brake lights being obscured. After the $300+ of fines it was a no brainer to contend with the minor PITA & install a light bar for my rack, especially when considering the outcomes of someone running up my arse while loaded with expensive bikes.
Vague question, were you by any chance pulled over for something else and had it added on, or just pulled over for the obscured lights?
It would be hard to imagine having a lower opinion of highway patrol than I do, but this might identify a new low
