Color of team number on the Bumper

Can we have a outline of a different color then white for more contrast to the numbers?

No; the only markings that are allowed are the ones required by R406, i.e. the white body of the number.

So no out line?

@vargoose84 Clarifying is probably more useful that copy-pasting the same text as the previous response.

@NIghtHawk, I’ve pasted the relevant portion of R406 below. You can only have white arabic numerals, so an outline would make the number either not a white numeral, or it would be another marking so with either way of looking at the outline it would not be allowed.

“consist of only white Arabic numerals at least 4 in. (~11 cm) high, at least ½ in. (~13 mm)
in stroke width”

You are correct, no outline.

Basically robot inspectors hate fun, so they want every set of bumpers to be easily identifiable and similar to every other set of bumpers. Please make it clearly blue/red fabric with easily readable numbers.

If you have to ask, then it is probably not in the spirit of the bumper rules.

(This is a joke, and I know robot inspectors don’t always hate fun)

I understand not wanting glitter on bumpers and things like that, but can anybody offer insight as to why this rule has been changed? A simple black outline does nothing but make the numerals more readable.

Since atleast 2014, outlining your bumpers numbers in BLACK has not be technically legal.

2014:

R28.A. consist of numerals at least 4 in. high, at least ½ in. in stroke width, and be either white in color or outlined in white,

R406 states that team numbers must

consist of only white Arabic numerals at least 4 in. (~11cm) high, at least 1/2 in. (~13mm) in stroke width,

I believe “only white” means that you should not put an outline on your numbers.

After reading the posts everyone’s been putting out here, it’s probably safest to just stick with the all-white numbering for now. If you can directly contact an inspector and get a definitive answer, then go with that.

A general rule of thumb about inspector rulings is if you aren’t sure, then don’t automatically assume that the ruling will go one way or the other. Either take the most clearly defined option or contact inspectors directly to see what their consensus is.
