Production Timeline and Key Changes
| Year Range | Headlight Style | Notable Features |
|---|---|---|
| 1987-1990 | Square | Sport roll bar, leaf springs |

Why Jeep Switched to Square Headlights

The square headlights weren’t merely an aesthetic choice—they represented broader modernization efforts, including improved aerodynamics, better lighting performance, and alignment with 1980s automotive design trends. The YJ also introduced wider track width and lower center of gravity, addressing the rollover concerns that had plagued its predecessor.
Interestingly, some enthusiasts jokingly claimed that “squares don’t roll,” referencing both the headlight design and the improved stability. While the headlight shape had no impact on vehicle dynamics, the YJ’s engineering improvements did deliver enhanced best Jeep Wrangler for daily driving characteristics compared to the CJ series.
