In zip-top plastic bag, or plastic container with a lid, mix together oil, garlic, Adobo Light and crushed red pepper. Add shrimp, tossing to combine; transfer to refrigerator. Chill shrimp at least 15 minutes, or up to 30 minutes.
Remove shrimp from marinade; reserve any remaining liquid. Alternately thread peppers, shrimp and lemon on metal or pre-soaked wooden skewers, so that each skewer starts and ends with peppers and contains 4 shrimp pieces. Using pastry brush, brush reserved marinade onto shrimp and vegetables.
Prepare grill to medium-high heat, or heat a heavy-bottomed grill pan over mediumhigh heat. Place shrimp on hot surface and cook until shrimp turn pink and opaque, flipping once, 3– 5 minutes. Remove from skewer before eating, if desired.
