150 Driver. You have two options.
1. Pass one of the alternative tests listed by the FAA. I will copy them to the end of this post. This results in a letter of competency stating that you meet the standards laid out in the FAR's. It is not considered a waiver.
2. Pass a signal light gun test at an FAA FDSO. This is straight forward enough. But you should go along to an airport before hand and ask the nice people in the tower if they could help you out by flashing the same lantern at you so you know if you are wasting your time or not.
I did my Titmus vision test at my ame's office in Irvine California. That may be a little bit out of your way.
here are the details for removal of the restriction as per AOPA (US)
Procedure for removal of color vision restriction
The newly revised standards in Part 67 specify that applicants for all classes of medical certification have "the ability to perceive those colors necessary for the safe performance of airman duties."
If the airman does not pass the color vision test administered in the Aviation Medical Examiner's office at the time of the FAA physical examination, the following options are available to remove the restrictions from the medical certificate:
(1) The more desirable option that does not result in the issuance of a waiver is the successful completion of an FAA-approved alternative test. The attached sheet from the Guide for Aviation Medical Examiners lists the optional tests and requirements for satisfactory completion based upon the class of medical applied for. The alternative test may be administered by an ophthalmologist or optometrist of your choice. Send successful results to the FAA and you will be issued an amended certificate without the night flight/color signal restriction. Instead of a Statement of Demonstrated Ability, the FAA issues a letter that you will present at each physical examination to verify that you meet the color vision standards.
There are several advantages to this option: (a) No authorization from FAA is necessary; (b) results of unsuccessful attempts need not be reported; (c) no SODA ("waiver") will be issued, so the airman need not claim a "waiver" (when applying for a professional flying position, for example); (d) if the airman is unsuccessful with an alternative test, the second option is still available.
(2) A "waiver" allows individuals who do not successfully pass the pseudoisochromatic color plate test administered in the medical examiner's office to have the night flying/color signal control limitation removed from their medical certificates by correctly identifying color signals flashed from an air traffic control tower.
*NOTE: THE COLOR SIGNAL LIGHT TEST CAN BE TAKEN ONLY TWICE.
IF YOU FAIL THE COLOR SIGNAL LIGHT TEST, THE FAA WILL NOT ALLOW YOU TO TAKE ONE OF THE OTHER ALTERNATIVE TESTS FOR REMOVAL OF THE NIGHT FLIGHT RESTRICTION. TRY THE OTHER ALTERNATIVE COLOR PLATE TESTS FIRST!
To be prepared for the color signal light test, we suggest you visit the airport and ask the tower specialist to flash the color signals in your direction. Have someone with you who has "normal" color vision to confirm that you correctly identify the colors. The FAA Inspector's Handbook also allows the inspector to ask you to demonstrate the ability to read aeronautical charts, including colored airspace and ground terrain designations most commonly found on sectional charts. You may or may not be asked to do this in addition to the light signal test.
Call the Aeromedical Certification Division in Oklahoma City and request an authorization for the color signal light test. Indicate the FAA Flight Standards District Office you intend to visit. The FAA will copy the authorization letter to that facility and to you. After receiving the letter, which is valid for 90 days, call the FSDO and schedule the test. Avoid midday tests when the sun is directly overhead. Late afternoon or cloudy days are the best conditions to view the light signals. Some facilities will accommodate an after-hours appointment if you ask.
Upon your successful completion of the test, the examiner will be authorized to issue the waiver (Statement of Demonstrated Ability) removing the restrictions from your medical. The FAA will usually upgrade a waiver to a higher class medical certificate without requiring a repeat of the signal light test.

Color Vision
(Attachment for Procedure for removal of color vision restriction)
CODE OF FEDERAL REGULATIONS
All Classes: 14 CFR 67.103(c), 67.203(c), and 67.303(c)
***ability to perceive those colors necessary for the safe performance of airman duties.
EXAMINATION PROCEDURES
Equipment
Pseudoisochromatic plates. (American Optical Company [AOC], 1965 edition; AOC-HRR, 2nd edition; Dvorine, 2nd edition; Ishihara, 14-, 24- or 38-plate editions; or Richmond, 1983 edition, 1 5-plates).
Acceptable substitutes:
Farnsworth Lantern
Keystone Orthoscope.
Keystone Telebinocular.
LKC Technologies, Inc., APT-5 Color Vision Tester.
OPTEC 2000 Vision Tester (Model Nos. 2000PM, 2000PAME, and 2000PI).
Titmus Vision Tester.
Titmus 11 Vision Tester (Model Nos. Tll and TIIS).
Titmus 2 Vision Tester Model Nos. T2A and T2S).
Techniques
The test plates to be used for each of the approved pseudoisochromatic tests are: Test Edition Plates
AOC 1965 1/15
AOC-HRR 2nd 1/11
Dvorine 2nd 1/15
Ishihara 14-plate 1/11
Ishihara 24-plate 1/15
Ishihara 38-plate 1/21
Richmond 1983 1/15
The following conditions should be ensured when testing with pseudoisochromatic plates:
The test book should be held 30 inches from the applicant.
Plates should be illuminated by at least 20-foot candles, preferably by a Macbeth Easel Lamp or a Verilux True Color Light (F1 5T8VLX).
Three seconds should be allowed for the applicant to interpret and respond to a given plate.
Testing procedures for the Farnsworth Lantern; Keystone; LKC Technologies, Inc.; OPTEC 2000, Titmus, Titmus II, and Titmus 2 Vision Testers accompany the instruments.
The results (normal or abnormal) should be recorded.
DISPOSITION
An applicant does not meet the color vision standard if testing reveals:
All Classes
Seven or more errors on plates 1-15 of the AOC (1965 edition) pseudoisochromatic plates.
AOC-HRR (second edition): Any error in test plates 7-11. Because the first 4 plates in the test book are for demonstration only, test plate 7 is actually the eleventh plate in the book. (See instruction booklet).
Seven or more errors on plates 1-15 of Dvorine pseudoisochromatic plates (second edition, 15 plates).
Six or more errors on plates 1-11 of the concise 14-plate edition of the Ishihara pseudoisochromatic plates. Seven or more errors on plates 1-15 of the 24-plate edition of Ishihara pseudoisochromatic plates. Nine or more errors on plates 1-21 of the 38-plate edition of Ishihara pseudoisochromatic plates.
Seven or more errors on plates 1-15 of the Richmond (1983 edition) pseudoisochromatic plates.
Farnsworth Lantern test: An average of more than one error per series of nine color pairs in series 2 and 3. (See instruction booklet).
Any errors in the six plates of the Titmus Vision Tester, the Titmus II Vision Tester, the Titmus 2 Vision Tester, the OPTEC 2000 Vision Tester, the Keystone Orthoscope, or Keystone Telebinocular.
LKC Technologies, Inc., APT-5 Color Vision Tester: The letter must be correctly identified in at least two of the three presentations of each test condition. (See APT-5 screening chart for FM-related testing in instruction booklet).
Certificate Limitation
If an applicant fails to meet the color vision standard as interpreted above but is otherwise qualified, the Examiner may issue a medical certificate bearing the limitation:
NOT VALID FOR NIGHT FLYING OR BY COLOR SIGNAL CONTROL.
Special Issuance of Medical Certificates
An applicant who holds a medical certificate bearing a color vision limitation may request reevaluation or a SODA under the special issuance section of Part 67 (14 CFR 67.401). This request should be in writing and should be directed to the Aeromedical Certification Division, AAM-300. If the applicant can perform the color vision tasks, the FM will issue a medical certificate without limitation with a SODA.
Demonstrating the ability to perform color vision tasks appropriate to the certificate applied for may entail a medical flight test or a signal light test. If a signal light test or medical flight test is required, the FAA will authorize the test. The signal light test may be given at any time during flight training. The medical flight test is most often required when an airman with borderline color vision wishes to upgrade a medical certificate.
X-Chrom Lens
This lens is not acceptable to the FAA as a means for correcting a pilot's color vision deficiencies.
Yarn Test
Yarn tests are not acceptable methods of testing for the FAA medical certificate
