Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 2000-2003 models is #4114K (trade number).

I have to replace my DTR's about every 3-6 months. The housing looks melted but still functional. I have considered replacing the wiring harness.
No fix..keep installing new bulbs, they keep burning out.
