will these burn out my harnesses or cause any other problems? they are for my sidemarkers on my dc clear bumper lenses

 

If you're replacing the stock wedge bulbs, they should be direct replacements. Therefore they shouldn't burn it out, cause the stock bulbs are rated at the same wattage and voltage....at least for the 5th gens. But I would think that the 4th and 5th gens are the same.
