Cadillac DTS Bulb Size By Years

tl;dr: This bulb size chart lists the correct replacement bulbs for a 2011 Cadillac DTS, saving you time and guesswork when you buy. I compiled this list from service manuals and hands‑on replacements, so it reflects real-world fit and function. Recommendation: Use the chart to match your bulb by location and type before ordering. Replacing headlights, turn signals, and interior lamps in the proper sequence reduces rework and prevents connector damage. I recommend confirming fitment on the part page and keeping an extra fuse when working on lighting. Impact and next steps: Using the right bulb avoids glare, uneven lighting, and warranty returns. Gotchas include halogen vs. LED compatibility and socket clips that fatigue. Affiliate disclaimer: some links on this page are affiliate links; I may earn a small commission at no extra cost to you.
