A vehicle lighting device comprising:

• a lamp housing;
• and
• a circuit board assembly disposed in the lamp housing, the circuit board assembly comprising:
• a circuit board having a circuit mounting surface;
• a first circuit component comprising an LED chip mounted on the circuit mounting surface;
• a second circuit component mounted on the circuit mounting surface;
• a first ribbon bond extending between the first and second circuit components, the first ribbon bond having a first end connected to the first circuit component and a second end connected to the second circuit component;
• a second ribbon bond extending between the first and second circuit components, the second ribbon bond having a first end connected to the first circuit component and a second end connected to the second circuit component;
• and
• an upstanding barrier structure extending on multiple sides of the first and second circuit components and having a ribbon bond guard extending at least partially over the first and second ribbon bonds, and a separator extending downward from the ribbon bond guard and at least partially between the first and second ribbon bonds.
